The sampling process¹ is full of delays and hidden fees. Each revision round costs valuable time and money, pushing your launch date back and straining your budget.

To streamline sampling, you must clarify the number of included revisions, get a detailed stage-by-stage timeline², use visual feedback³, and ask for digital mockups to confirm designs before cutting fabric.

I've seen so many talented designers get stuck in the "sampling loop." They spend months and thousands of dollars on revisions that could have been avoided.

A good factory partner works with you to get the sample right as efficiently as possible. It's about clear communication and a structured process, not endless guesswork.

Getting this first step right is critical, as it sets the tone for the entire production run. Let's break down how to take control of the sampling process¹.

How Many Prototype Iterations Are Included in My Sample Fee?

You pay a sample fee, but you're not sure what it covers. You ask for a small change and suddenly receive another bill, complicating your budget and causing frustration.

Most sample fee⁴s cover one initial prototype plus one revision. You must ask your factory to confirm this in writing. Always clarify the cost of any additional rounds upfront.

The sample fee should never be a mystery. From a factory's perspective, each sample takes time from our most skilled pattern makers and sewing machine operators.

That is why the fee exists. However, a professional factory will be transparent about what you get for your money.

Think of it in two steps: the first prototype (Proto) is for us to get the basic fit and construction right. The first revision is to fine-tune the details based on your feedback.

If you need major changes, like a completely new fit, it is fair to expect that might count as a new sample with a new fee. Always have this conversation before you send any money.

Clarifying What's Included

• Minor vs. Major Changes: Ask the factory to define the difference. Changing a thread color is a minor tweak. Changing the entire pattern from a slim fit to a straight fit is a major change.
• Negotiate Upfront: If you know your design is complex, try to negotiate a package. You can say, "We plan on a 1,000-piece bulk order. Can you include two revision rounds in our initial sample fee?" This shows you're a serious partner and helps them invest in the relationship early.

What Is the Typical Turnaround Time Per Sampling Phase?

The factory tells you "7-10 days" for a sample, but weeks go by. This vagueness stalls your entire project, leaving you unable to plan photoshoots or marketing campaigns.

A prototype sample takes 5-7 days to make, but that is after the fabric arrives. Sourcing fabric can add another 7-14 days. Always ask for a timeline broken down by phase.

The biggest mistake I see brands make is not accounting for fabric and material sourcing time. A factory cannot start your sample until they have the denim, buttons, and zippers in their hands.

If you are using a standard denim that we have in stock, the process is fast. If we need to order a custom-milled organic denim for you, that alone can take weeks.

A good partner will be honest about this and give you a clear, phase-by-phase schedule. Your planning depends on this information.

You need to know the realistic timeline for each step to manage your entire go-to-market strategy effectively.

A More Realistic Timeline

Phase	Description	Estimated Time
Fabric & Trim Sourcing	We order and receive your specific denim and hardware.	7-14 days (standard) / 15-25 days (custom)
Initial Proto Sample	We create the first physical sample for fit.	5-7 days
Your Review & Feedback	You receive the sample and provide your notes.	1-3 days
Revision Sample	We create a new sample based on your feedback.	3-5 days

What’s the Best Way to Submit Feedback to Expedite Revisions?

You send emails explaining what's wrong, but the next sample still has the same errors. This communication breakdown is frustrating and leads to an endless cycle of costly revisions.

The best feedback is visual. Send photos of the sample with markings and comments. Combine these with a clear, written list of changes that references specific measurements from your spec sheet.

Vague feedback is the number one cause of sampling delays. Comments like "the fit is weird" or "make the wash lighter" are impossible for my team to interpret correctly.

You have to be incredibly specific. The most effective method is to create a single feedback document for each revision. Take clear photos of the sample, on a model or a flat surface.

Use a simple editing tool to draw arrows and write notes directly on the images. For example, circle the waistband and write, "Waist measures 85cm. Spec is 83cm. Please reduce by 2cm."

This combination of a visual guide and precise data from your spec sheet removes all guesswork. It also helps to nominate one person on your team as the single point of contact.

This prevents my team from receiving confusing, and sometimes conflicting, feedback from different people.

Are Digital Mockups Available Before Cutting Physical Samples?

Creating multiple physical samples to test small ideas is slow and expensive. You want to see how a design looks without committing the time and money to a full physical prototype.

Yes, many modern factories can provide digital mockups⁵ (2D or 3D renderings). This is a fast and low-cost way to review things like embroidery placement or wash effects before cutting any fabric.

Digital mockups are a powerful tool to speed up the development process.

Before we cut a single piece of your expensive denim, we can create a digital rendering of your design. This is perfect for visualizing details that are hard to describe in a tech pack.

For example, we can show you three different placement options for your back pocket embroidery so you can choose the one that looks best.

We can also create a digital simulation of a wash effect to get the color and distressing level right before it ever touches water.

Some factories include this for free, while others charge a small fee. It is always worth asking.

This one step can often save you an entire round of physical revisions, saving you both time and money. It is a smart way to work out the creative details quickly.

Conclusion

A structured sampling process with clear communication is key. It eliminates guesswork, saves money, and gets your final, perfect product into production faster, which is a win for everyone.
