‘Make the pocket bigger’ is not a usable sample instruction. The pattern maker needs to know which dimensions change, what must stay fixed and how the next sample will be judged. For a Weierken bag project, one marked revision sheet can connect your product decision to pattern development, sample making and the final approval.
Turn a comment into one controlled change
Worked example, not a real customer project: a buyer wants a larger front pocket on a cooler backpack. All dimensions below illustrate how to write the instruction; they are not specifications for a Weierken model.
| Detail | R01 reference | R02 request | Check on the revised sample |
|---|---|---|---|
| Pocket finished size | 160 mm wide × 180 mm high | 180 mm wide × 200 mm high | Measure the finished pocket using the agreed measurement points. |
| Bag body | Approved outline and dimensions | No change | Compare the body with R01; do not enlarge the whole bag. |
| Carry attachments | Existing strap anchor positions | Keep positions fixed | Check clearance between the enlarged pocket, seams and anchors. |
| Access | Original pocket opening | Fit the buyer’s device in its case | Load the actual device; check removal with the main bag packed. |
Put labels A–D on a front-view photograph to match these four rows. A should point to pocket width, B to height, C to the nearest strap anchor and D to the opening. Include arrows and measurement endpoints, not just a circle around the entire pocket.
Resolve the knock-on effects before cutting again
Weierken’s design and sample development covers bag structure and pattern work. Use that capability to review whether the requested pocket changes panel space, seam access, logo position or the internal volume. Ask the team to flag conflicts on the same drawing, so commercial and technical replies refer to one revision.
A larger pocket may fit on the front view but collide with a handle when loaded. Resolve that conflict as an explicit choice: revise the pocket, move an attachment with approval, or leave the original arrangement. Do not allow a helpful but unrecorded change to create a second, hidden specification.
Release a revision, not a collection of messages
- Name the files consistently: Project-B / R02 / front-pocket drawing, change sheet and sample photos.
- Record each item as accepted, rejected or still open. ‘Looks better’ is not approval of dimensions or materials.
- Assign the buyer’s approval contact and request a development response against each row. Keep unanswered rows open.
- On acceptance, archive R01 as superseded and issue one R02 reference pack to everyone reviewing the order.
Use the sample approval checklist for the final release. A corrected pocket does not automatically approve color, lining, hardware or packing that were outside this revision.
Frequently Asked Questions
What if two colleagues send conflicting changes?
Nominate one buyer-side approver to issue a consolidated instruction. Weierken should receive the selected requirement, not be asked to choose between different commercial intentions.
Will a revision require another sample or an additional charge?
That depends on the affected construction and agreed sample scope. Send the marked change sheet and request confirmation of the work, charge and timing before it begins.
