The Bag Sampling Process: What Each Round Is Really For, and Why Yours Is on Round Four

Somebody told you two to three rounds is normal.

You’re on round four. The strap keeps coming back a centimetre short, the gusset still doesn’t stand up, and the launch date hasn’t moved. So either the factory is incompetent, or you’re being difficult, and neither of those explanations is doing you any good on a Tuesday afternoon with a season to fill.

Try a different one.

You are not paying for a sample. You are paying to find out what you forgot to put in the tech pack. Every round is the specification finishing itself, one omission at a time. That’s not a failure of the process. That is the process — and once you see it that way, the question stops being how do I get fewer rounds and becomes how do I move the rounds somewhere they’re cheap.

There’s a second thing nobody tells you, and it’s the one that decides whether any of this was worth doing. It has nothing to do with how many rounds you ran. It’s about where the sample was physically made, and we’ll get to it, because it’s the difference between a sample that predicts your bulk and a sample that lies to you.

How long does a bag sample actually take?

Seven to fourteen days for a first sample on a normal custom bag, if the materials are in the building. Longer the moment anything has to be sourced, dyed, or tooled. A rush sample can go faster, but “faster” is a decision about what you’re willing to skip, not a decision about how hard people work.

The honest breakdown of where a sample week goes:

Look at row three. Material availability, not sewing skill, is what decides your sample lead time. A factory quoting you 7 days is quoting you 7 days on stock material. Ask for a custom Pantone and the same factory, with the same team, honestly needs three weeks — and the three weeks are happening at a dye house nobody in this conversation controls.

This is the first place you can move a round. If you’re time-boxed, sample in a stock colour with the correct construction, approve the build, then do a colour-only round later. You’ve split one slow round into one fast round and one trivial one. Most brands do the opposite and wait three weeks to discover the strap is too short.

How many rounds is normal, and what is each round actually for?

Three to four rounds is normal for a genuinely custom bag, and every guide that tells you “two to three” is quoting apparel numbers at you. Bags don’t have fit samples. Bags don’t have size runs. What bags have is structure, and structure fails in a specific order.

Here’s the sequence that actually happens, whether or not anyone names it:

Notice what rounds 1 through 3 have in common. None of them are aesthetic. They’re all information you didn’t have, and couldn’t have had, until something physical existed.

Which means the rounds aren’t the enemy. Ambiguity is the enemy, and rounds are just the expensive way of resolving it. Every ambiguity you leave in the tech pack becomes a round. Every round is two to three weeks and a courier bill.

So: what actually kills rounds?

• Dimensions with tolerances, not dimensions. “Strap 60cm” gets you a 60cm strap. “Strap 60cm ±0.5, measured from webbing edge to buckle bar” gets you the strap you meant.
• Named hardware. “Gold buckle” is a round. “YKK #5 metal, antique brass, 25mm” is not.
• A reference bag in the room. Not a photo. A physical bag you can cut open. Any pattern maker will tell you one reference bag is worth thirty reference images, and photos are where “it looked bigger online” comes from.
• A stated intent per feature. Say why the pocket is there. A pattern maker who knows the pocket holds a 14″ laptop will build it correctly. A pattern maker who only knows it’s 35cm wide will build it exactly 35cm wide and slightly wrong.

None of that is glamorous. All of it is cheaper than a round. There’s a longer version of this in our guide to designing a bag from the manufacturing side, which is really a guide to how designs fail in a pattern room.

A word on the round count itself. Most brand clients we work with revise several times, and they should. A brand that approves the first sample without changing a thing either sent an unusually complete tech pack, or isn’t looking hard enough. Neither the factory nor you should treat “more rounds” as a scoreboard — the only question that matters is whether each round bought you information or just bought you a week.

What does a bag sample cost, and why won’t they just tell you?

Typically $80–$400 for a custom bag sample, and the number is mostly labour, not materials. You’re buying a pattern maker’s day, not a bag. Which is exactly why nobody can quote it off a photograph.

What’s actually inside the number:

• Pattern development. The largest line. A pattern for a new bag can take a skilled maker one to three days, and that pattern is reusable, which is why round two is usually cheaper than round one.
• Material at sample quantity. You are buying two metres of a fabric that costs what two metres costs, not what 2,000 metres costs. This is why sample-stage material feels wildly overpriced. It is. That’s not a markup; it’s the absence of volume.
• Hardware. Off-the-shelf: pennies. Custom mold: hundreds to low thousands, and it’s a tooling charge, not a sample charge. (It’s also an assist for customs purposes if you take ownership of the mold, which is a whole other conversation and a real one.)
• Courier. $40–$100, and it will annoy you every time.

Three things worth negotiating, none of which is the sticker price:

Get the sample fee credited against the first bulk order. This is common, it’s reasonable, and most factories will agree to it if you ask before the sample, not after. Get it in writing in the PI.

Ask which rounds are included. A quote that covers “the sample” and a quote that covers “the sample plus two revisions” are different products at the same price. Vadalo, an Indian bag maker, publishes exactly this: two revision rounds included, more billed at the re-sampling rate. Most factories have the same policy and just don’t publish it. Ask.

Don’t shop for the cheapest sample. This is the one place in the entire project where cheap is genuinely stupid. A $60 sample from a factory with no pattern room and a $250 sample from a factory with one are not the same transaction, and the difference shows up eight weeks later in a shipping container. Which brings us to the part that actually matters.

Where was your sample physically made?

Ask this question. It is the single most predictive question in bag sourcing, and almost nobody asks it.

A large share of bag factories in China do not make their own samples. They send the job out to an independent pattern house — a banfang — a small workshop of specialists who make beautiful prototypes for a dozen factories at once.

Think about what that means.

The people who made your sample are not the people who will make your bulk. Different building, different machines, different hands, different tension settings, different standards. The sample was made by craftsmen taking three days over one bag. Your bulk will be made by a line taking eleven minutes over each of five thousand.

Then the sample comes back, it’s lovely, you approve it — and the factory now has to reverse-engineer a production process for a bag they didn’t develop, using an approved standard they had no hand in setting. And the first time anyone finds out that the reinforced corner is unbuildable at line speed is somewhere around unit 400.

This is the mechanism behind the sample-versus-bulk gap, the number one complaint in this entire industry. It isn’t usually fraud. It’s a handoff nobody told you existed.

A factory with its own sample room is doing something structurally different, and the difference has nothing to do with speed:

• The pattern maker who develops your bag is in the same building as the line that will produce it, and will be asked awkward questions by that line’s supervisor.
• Manufacturability gets caught during sampling, not during production. A sample maker who knows the bulk is coming to his own floor will tell you a construction is a bad idea at round two, instead of building it beautifully and letting you find out later.
• The approved sample is a standard the factory can actually hit, because they set it themselves.

Meyzy runs a 450㎡ prototype workshop in-house, which you can see on our capabilities page. We mention it here not as a boast but because it’s the answer to a question you should be putting to every factory you’re evaluating, including us:

“Do you make samples in your own building, or do you send them out? Can I see the sample room on video, today?”

A factory that samples in-house will show you the room in about four minutes. A factory that outsources will explain why the question doesn’t matter. That explanation is your answer.

The last round is not a sample. It’s a contract.

The sample you finally approve stops being a prototype the moment you sign it. It becomes the acceptance standard for every one of the 5,000 bags behind it. Everything you checked, you get. Everything you didn’t check, you get whatever the factory decided.

This is why the final round deserves a different kind of attention from the ones before it. Rounds 1 to 3, you’re asking is this the bag I want? Round 4, you’re asking is this the bag I can hold them to?

Which means: signed, dated, sealed, one copy at the factory and one with you. Named in the Proforma Invoice as the quality reference. Paired with an AQL level and a defect classification, so that “this doesn’t match the sample” is a claim an inspector can actually make. We’ve written the full pre-bulk approval checklist separately, because it’s a different job from the one this article describes.

How to run a sampling round so it isn’t wasted

Nothing here is complicated. All of it gets skipped.

• Send a tech pack, not a photo. Every round you save pays for the day it took to write. Start from the RFQ checklist.
• Send a physical reference bag if one exists. Overnight it. It’s worth a week.
• Ask where the sample will be made before you pay the sample fee.
• Sample in stock material if you’re time-boxed. Approve the build first, colour second.
• Give feedback in one document, with photographs and measurements. Six WeChat messages across two days is how round five happens.
• Say why, not just what. “Strap 5cm longer” gets you 5cm. “It needs to clear a winter coat” gets you a strap that works.
• Agree in writing how many revisions are included and whether the fee credits against bulk.
• Treat the final sample as a legal document, because it is.

Sampling is the cheapest part of a bag project and the only part where mistakes are still reversible. A round costs you a few hundred dollars and two weeks. The same mistake discovered in bulk costs you the run, the season, and — if it reaches your customers — the reason they trusted you.

Spend the money here. Spend the rounds here. Just make sure the room they’re being made in is the same room your bulk will come out of.

If you want a sampling plan with the rounds mapped before you spend the first dollar — including which decisions to make in stock fabric and which to hold for later — send us the design and we’ll come back with a schedule, not a slogan. Our development capabilities page covers what happens after that.
