Knitted Bag Selection Matrix: Nine Weighted Criteria From a Range Review
How do you choose between a knitted, a woven and a mesh bag body without arguing from preference? Weight nine criteria before you score them. In a six-SKU range review that is exactly what happened, and the result was knit 3.90, woven 3.62 and mesh 3.05 out of five. Knit won on minimum fit, lead time and sustainability; it lost on unit cost at 3 against 5 and on printed logo detail at 2 against 5, and both losses were real.
The Range Review: Six SKUs, Three Routes
A home and lifestyle retailer was rebuilding a reusable bag range around six stock-keeping units: one large shopper, one medium shopper, one produce bag, one bottle carrier, one laundry bag and one gift pouch. Annual volume was about 34,000 pieces, spread unevenly — the large shopper took about 40% of it and the gift pouch about 4%. Three fabrication routes were on the table: seamless weft knit, cut and sew canvas, and warp-knitted mesh.
The buying team had been arguing for two meetings without progress, because each route had a champion and each champion had a number. The way out was a weighted matrix: agree the criteria and their weights first, while nobody knows how the routes will score, then score. That order matters. Weighting after scoring is just arithmetic applied to a decision someone already made.
Building the Weighting Before the Scoring
Nine criteria were agreed, with weights that reflected how the retailer actually makes money. Unit cost carried 20%, because the range sits at a fixed retail price band. Minimum order fit carried 15%, because the retailer wanted to test six colourways. Lead time carried 15%, because the shelf date is fixed by a campaign calendar. Durability carried 15%, because the range carries a two-year guarantee.
The remaining five shared the last 35%: appearance 10%, sustainability 10%, logo execution 5%, packing and freight 5%, and supply risk 5%. Weights were fixed before any route was scored, and each score ran from 1 to 5 against evidence rather than opinion — a test report, a quotation or a confirmed calendar, not a preference. Anything without evidence scored 3 by default.
Criterion One: Unit Cost, Weighted at 20%
This is the row knit loses, and it lost it by two points: 3 against 5 for cut and sew canvas. At the range volume the canvas route quoted about USD 4.40 per blended unit against about USD 5.20 for the knit and about USD 3.10 for mesh. On 34,000 pieces that is a difference of roughly USD 27,000 a year in favour of canvas, which is a serious number and the reason this criterion carries the heaviest weight.
What softens it in practice is that the blended figure hides the shape of the range. The gift pouch at about 1,400 pieces a year is badly served by a canvas route that wants a larger cutting run, and the produce bag at about 2,100 pieces needs an open structure that canvas does not provide. A single blended unit cost is the least informative number in most range reviews, and this one was no exception.
Criterion Two and Three: Minimum Fit and Lead Time
Minimum order fit is where knit runs away from the field. At 100 pcs per style and colourway, six SKUs commit the retailer to about 600 pieces, and a colourway test on any single SKU costs 100 pieces. The canvas route wanted a larger run per colourway to make the marker and the cutting setup worthwhile, which pushed the test quantity up and put the six-colourway plan out of reach. Knit scored 5, canvas 3 and mesh 4.
Lead time scored the same way: knit 5, canvas 3, mesh 3. Sampling runs 7 working days for a knitted body and 30 days for bulk after approval, so a revised colourway reaches the shelf in about six weeks. A canvas revision needs a reissued pattern and a fresh cutting trial, normally 12 to 15 working days for sampling alone. Across a campaign calendar with four drops a year, that difference is roughly a month of shelf life.
| Criterion | Weight | Seamless knit | Cut and sew canvas | Warp-knitted mesh |
|---|---|---|---|---|
| Unit cost | 20% | 3 | 5 | 4 |
| Minimum order fit | 15% | 5 | 3 | 4 |
| Lead time | 15% | 5 | 3 | 3 |
| Durability | 15% | 4 | 4 | 2 |
| Appearance | 10% | 4 | 4 | 3 |
| Sustainability | 10% | 5 | 3 | 3 |
| Logo execution | 5% | 2 | 5 | 2 |
| Packing and freight | 5% | 4 | 3 | 5 |
| Supply risk | 5% | 4 | 4 | 3 |
| Weighted total | 100% | 3.90 | 3.62 | 3.05 |
The weighted total is close enough that the honest reading is not "knit wins" but "knit wins narrowly on this retailer's weights". Change the weighting and the answer moves. A promotion house that sells one design at 200,000 pieces and never changes it would weight unit cost at 50%, and canvas would win by a distance. The matrix is a tool for making the weighting explicit, not a verdict. It is also a record: when a colleague asks in eighteen months why the range went to knit, the sheet answers with weights and scores rather than with recollection.
Criterion Four and Five: Durability and Appearance
Durability was scored from test evidence rather than from reputation. A 600D knit reaches about 25,000 rubs to ISO 12947-2 at 12 kPa, canvas about 15,000 and a 200D monofilament mesh about 8,000, so knit and canvas tied at 4 and mesh scored 2. That tie was surprising to the team, who had assumed canvas would win, and it is the clearest example of why evidence-based scoring changes minds.
Appearance is the row where scoring is genuinely subjective, and the team handled it by sampling instead of arguing. All three routes were sampled in the same two shades and put on a shelf under retail lighting, then scored by three people independently. Knit and canvas both scored 4 and mesh 3. The exercise cost one extra sampling round and removed an argument that had consumed two meetings.
Criterion Six to Nine: Sustainability, Logo, Packing and Risk
Sustainability scored knit 5 against 3 for both alternatives, on a single issue: monomaterial construction. A knitted body in one recycled polyester grade, with matching thread and webbing, enters a single polymer stream. Canvas is usually cotton with polyester thread and a printed label, and mesh is often polypropylene. Under an extended producer responsibility scheme that charges by material complexity, that row has a cash value, not just a marketing one.
Logo execution is the second row knit loses badly, scoring 2 against 5 for canvas. A flat woven panel accepts a four-colour process print at about 0.2 mm resolution; a knitted-in logo has a practical minimum stroke near 1.5 mm and cannot reproduce a photograph. Packing and freight went the other way, mesh 5 and knit 4, because both fold flat and nest. Supply risk scored knit and canvas 4, mesh 3, reflecting how many machines can run each route.
Where Knit Lost, and What the Team Did About It
Two losses were real and were not argued away. Unit cost: the canvas route is genuinely about USD 0.80 lower per blended unit, which is about USD 27,000 a year on this range. Logo execution: the retailer's gift pouch carried a photographic seasonal image, and a knitted body cannot reproduce it at acceptable quality. Pretending either would not be true would have discredited the whole exercise.
The response was to split the range rather than to force a single route. The large shopper, the medium shopper and the bottle carrier went to knit, taking about 78% of the volume and the weighted advantages on minimum fit, lead time and sustainability. The gift pouch went to canvas because the artwork demanded it. The produce bag and the laundry bag went to mesh because air permeability decides those briefs outright.
Weight before scoring
Fix the weights while nobody knows the scores. Weighting after scoring is arithmetic applied to a decision already made.
Score on evidence
A test report, a quotation or a confirmed calendar. Anything without evidence defaults to 3, which stops opinion becoming a number.
Sample the subjective rows
Appearance cannot be argued into a score. Sample all routes in the same shade and put them under retail lighting.
Split rather than force
A narrow total means the routes are close, and the best answer is usually per-SKU rather than per-range.
How to Reuse This Matrix on Your Own Range
Start with the nine criteria and change the weights to match how your business makes money. A promotional buyer should weight unit cost at 40 to 50% and minimum fit near zero, because the design never changes. A fashion retailer should weight minimum fit and lead time highest, because the range refreshes every season. A corporate gifting programme should weight logo execution far higher than this retailer did.
Then insist on evidence for every score. Ask for the abrasion report to ISO 12947-2, the tensile figure to ISO 13934-1, the confirmed sampling calendar, the minimum per colourway in writing and the freight volume per 500 pieces. A matrix built on estimates produces a total that looks authoritative and is worthless, which is worse than no matrix at all.
Turning the Score Into a Purchase Order
A weighted total is a decision aid, not a specification. Once the routes are assigned, each SKU still needs a written specification: dimensions, rated load, yarn count and gauge, finished mass with a tolerance, abrasion target, and inspection level. The matrix tells you which route to buy; the specification tells the production team what to make, and only the second document prevents disputes.
For this retailer the follow-up was straightforward. The three knitted SKUs were placed on one yarn count so they could share a cone lot, at 100 pcs per style and colourway, with 7 working day sampling and 30-day bulk, FOB Xiamen and inspected to AQL 2.5 under ISO 2859-1. The canvas and mesh SKUs kept their own calendars. Capacity across 7 production lines was booked in writing before the launch date was confirmed.

Frequently Asked Questions
What is a bag selection matrix?
A weighted scoring table that compares fabrication routes against criteria agreed in advance. Nine criteria are usually enough: unit cost, minimum order fit, lead time, durability, appearance, sustainability, logo execution, packing and freight, and supply risk. The weights are fixed before scoring so the total reflects the business rather than the preference.
How should I weight the criteria?
Match the weights to how the business makes money. A promotional buyer selling one design at high volume should weight unit cost at 40 to 50%. A fashion retailer refreshing every season should weight minimum fit and lead time highest. A corporate gifting programme should weight logo execution heavily.
Which route won the six-SKU review?
Seamless knit, at 3.90 against 3.62 for cut and sew canvas and 3.05 for warp-knitted mesh. The margin was narrow, and the practical outcome was a split: three SKUs to knit, one to canvas because of photographic artwork, and two to mesh because air permeability decided them.
Where does knitting lose in a weighted matrix?
Two rows. Unit cost, scoring 3 against 5 for canvas, because the canvas route quoted about USD 4.40 per blended unit against about USD 5.20. And logo execution, scoring 2 against 5, because a knitted-in logo has a practical minimum stroke of about 1.5 mm and cannot reproduce a photograph.
How is durability scored objectively?
From test reports rather than reputation. A 600D knit reaches about 25,000 rubs to ISO 12947-2 at 12 kPa, canvas about 15,000 and a 200D monofilament mesh about 8,000. Adding tensile to ISO 13934-1 on the handle root gives a second number, and together they make the row defensible.
Should appearance be scored in a matrix?
Yes, but sample it rather than argue it. Make all routes in the same two shades, put them under retail lighting and have three people score independently. On this review knit and canvas both scored 4 and mesh 3, and one sampling round replaced two meetings of debate.
What score should I give a criterion with no evidence?
Give it 3 by default. Defaulting prevents an unevidenced opinion from becoming a number that carries weight in the total. It also creates a useful to-do list: every row sitting at 3 without evidence is a question to ask the shortlisted partner before placing an order.
Is the weighted total the final decision?
No. It tells you which route to buy, not what to make. Each SKU still needs a written specification with dimensions, rated load, yarn count and gauge, finished mass and tolerance, abrasion target and inspection level. Only that document prevents disputes at bulk, because it is what the production team actually works to.
How many pieces does a six-SKU knitted range commit?
About 600 pieces at 100 pcs per style and colourway, which is the practical reason knit wins the minimum-fit row. A colourway test on any single SKU costs 100 pieces, so a retailer can test six shades across the range for the quantity a canvas route needs for one.
Does sustainability really change the ranking?
Yes, when it is scored as monomaterial construction rather than as a claim. A knitted body in one recycled polyester grade with matching thread and webbing enters a single polymer stream, while canvas with polyester thread and a printed label does not. Under extended producer responsibility fees that has a cash value.
What is the lead time advantage worth?
About a month of shelf life across a year. Sampling runs 7 working days for a knitted body against 12 to 15 working days for a reissued canvas pattern, and bulk is 30 days either way. Across four drops a year that compounds into roughly four extra weeks of selling time.
Can one range use three different routes?
Yes, and it is usually the right outcome when the weighted total is narrow. Assign per SKU: knit for the high-volume items that refresh, canvas where photographic artwork is required, and mesh where drainage or air flow decides the brief. Then give each SKU its own calendar and specification.
People Also Ask
How do you compare bag materials objectively?
Weight nine criteria before scoring, then score each route 1 to 5 on evidence such as a test report or a quotation. Unit cost, minimum fit, lead time and durability usually carry 15 to 20% each. Anything without evidence defaults to 3.
Which bag construction scores best overall?
On this six-SKU review, seamless knit at 3.90 out of five, against 3.62 for cut and sew canvas and 3.05 for mesh. The margin is narrow, and the practical answer was to split the range by SKU rather than to pick one route.
Why does knitting lose on printed logos?
A flat woven panel resolves detail to about 0.2 mm and takes four-colour process print. A knitted-in logo has a practical minimum stroke of about 1.5 mm. A heat transfer reaches about 0.4 mm but adds a polymer layer that complicates recycling.
How much does unit cost matter in a bag range?
Weighted at 20% in this review, it is the single heaviest row. Canvas quoted about USD 4.40 per blended unit against about USD 5.20 for knit, roughly USD 27,000 a year on 34,000 pieces. A promotional buyer should weight it far higher.
Is a weighted matrix better than a simple comparison?
Yes, because it forces the weighting into the open. A simple comparison hides the fact that two people are arguing from different priorities. Once the weights are written down, the disagreement becomes a discussion about the weights instead of about the fabric.

What the Matrix Cannot Tell You
A weighted matrix will not resolve a brief that is internally contradictory. If the range must be the lowest unit price, refresh four times a year and carry photographic artwork, no route satisfies all three, and the correct answer is to change the brief rather than to find a fabric. Say so early, because the alternative is a specification nobody can quote honestly.
The matrix also cannot substitute for sampling. Scores on durability, appearance and logo execution are predictions until a physical sample exists, and one sampling round at 7 working days is a small price against a full season of the wrong construction. Keep the scoring sheet with the specification pack, because the next range review should start from the previous weights and argue only about what changed. If the weighting has not changed and the evidence has not changed, the answer should not change either, and that consistency is what makes the matrix worth maintaining.
