Samples and prototypes
Last updated: November 2026
You cut sampling rework by sending a complete tech pack or product specification before the first sample, then recording every comment against that document.
Right Prototypes is step two of Cydney Mar's Concept-to-Reality Pathway: develop the right samples and cut costly rework. This Spec to Shelf guide explains the sample stages, why extra rounds happen, and includes an estimator built on Techpacker's published rework cost range.
A prototype tests whether the idea works and looks right. A sample is made by the intended supplier to show how the product will actually be produced. You usually need both, in that order.
| Stage | Purpose | Made by | What you approve |
|---|---|---|---|
| Prototype | Prove the idea works and looks right | You, a maker or a sample room | The concept |
| Development sample | Test the spec with the chosen materials | The intended supplier | Fit, function and construction |
| Pre-production sample | Confirm exactly what bulk will look like | The production supplier | The final product, signed off |
| Production check | Confirm bulk matches the approved sample | Pulled from the production run | Consistency before shipping |
Most extra rounds trace back to one of four gaps, and each one is fixable on paper.
Definition
A sampling round is one full cycle of sending a specification, receiving a physical sample, reviewing it, and returning comments. Every round repeats pattern or tooling changes, materials, labor, shipping and waiting time. Cydney Mar names jumping into sampling without clarity as one of the most common reasons founders lose time and money.
Estimate what extra garment sampling rounds could cost, using the only published figure supplied for this guide. Enter whole numbers.
Assumptions: uses Techpacker's published figure that correcting garment defaults adds $1,500 to $5,000 per style in rework costs per sampling round, multiplied by your styles and extra rounds. This is an estimate for planning only, not a quote or financial advice. Your real cost depends on your product, factory and region.
A prototype tests whether an idea works and looks right; a sample is made by the intended supplier to show how the product will actually be produced. Founders often move from a proof-of-concept prototype to development samples, then to a pre-production sample that is approved before bulk production starts.
More in the FAQExpect more than one, and fewer when your specifications are complete. The number depends on product complexity, how clear the tech pack or spec sheet is, and how quickly comments go back to the factory. The Right Prototypes step in Cydney Mar’s pathway focuses on developing the right samples and cutting costly rework.
More in the FAQEvery extra sample round repeats pattern changes, materials, labor, shipping and weeks of waiting. Techpacker's 2026 guide puts the cost of correcting garment defaults at $1,500 to $5,000 per style in rework costs per sampling round. Clear specifications before the first sample are the main way founders cut the number of rounds.
More in the FAQWhen samples keep coming back wrong, pause and check the specification before ordering another round. Common causes are missing measurements or tolerances, vague construction notes, and comments that do not reference the spec. Fix the document first, then resample. Cydney Mar’s work includes tech packs, sampling and hands-on product development for founders stuck at this stage.
More in the FAQA tech pack’s cost depends on the style’s complexity, the number of sizes graded, and who builds it, so there is no single price. Cydney Mar does not list prices on her website. A useful benchmark is the cost of not having one: Techpacker reports that correcting garment defaults adds $1,500 to $5,000 per style in rework costs per sampling round.
More in the FAQStart with clear front and back flat sketches, then add a bill of materials listing every fabric, trim and label. Build a measurement chart with points of measure and tolerances, add construction notes for seams and finishes, then colorways and packaging. Review it against a physical reference or first sample and revise. The step by step version is in the tech pack garment guide on this site.
