v0.16 — Applying Bottom Binding Layers

Building Masters | 123 | Phase 4

Last Updated: May 5, 2026

 

FINISHING LAYERS

Overview

In this lesson, you will learn how to update the bottom binding so it matches the target size and sits correctly on the garment.

You will start by turning on the bottom binding layer, confirming that it is positioned at the bottom of the jersey, and checking that it matches the adult large reference, including the 2-inch taller hem on each side. Then you will extract the bottom binding from the existing setup, align it precisely to the bottom of the front and back panels, and copy and paste it into the appropriate layers so both panels share the correct binding.

STEP-by-STep guide

1. Start the bottom binding setup and confirm the target size 0:00

generated-image-at-00:00:00

  • Begin by switching to the new day’s file/version.

  • Turn on the bottom binding training/workflow.

  • For 2D patterns, delete the existing setup so you can rebuild it cleanly.

  • Confirm that bottom binding is not graded by size because the hem is the same across all sizes.

  • Verify the correct size and that the binding is set to the bottom position.

2. Check front and back bottom binding symbols 1:36

  • Pull out the bottom binding symbol for the front.

  • Verify:

    • the size is correct (example shown: Large)

    • the placement is set to bottom

  • Repeat the same check for the back bottom binding symbol.

  • Confirm the front and back symbols match the expected IDs/versions before continuing.

3. Extract the old bottom binding from the existing patterns 4:04

  • Remove the old bottom binding from the existing clipped pattern setup.

  • Extract the bottom binding from the old patterns rather than rebuilding everything from scratch.

  • Double-check that the extracted pieces still match the expected size values.

  • If anything is still open or not extracted correctly, keep it open and verify again before moving on.

4. Copy and align the bottom binding for the front and back panels 5:46

  • Copy and paste the bottom binding pieces as needed.

  • Align the bottom binding symbols to the bottom edge of the:

    • Front panel

    • Back panel

  • Make sure the bindings sit correctly in relation to each panel before moving to the side panels.

5. Move to the side panels and bring in the production pieces 6:35

  • Go to the side panels next.

  • Bring all production side-panel pieces into the working file.

  • Use layer navigation shortcuts to move pieces up or down efficiently.

  • Open the side-panel clipping mask that was just added.

6. Extract and replace the side-panel bottom binding 9:42

  • Inside the side-panel clipping mask, extract the existing side-panel pieces.

  • Delete only the pieces that belong to the bottom binding layer.

  • Do not delete pieces from the side-panel layer itself.

  • Replace the old side-panel bottom binding with the new one.

  • Note that some pieces may remain because they belong to a different side panel or orientation.

7. Understand why the clipping-mask setup speeds up the process 14:02

  • The front/back and back/front pieces lock into place in a predictable way.

  • Because the clipping masks were already set up earlier, you can now copy and paste them instead of rebuilding them.

  • This makes the process much faster once the initial setup is complete.

  • After pasting, you still need to extract the old pieces and insert the new bottom binding.

8. Verify 1D and 3D side-panel sizing differences 15:32

  • Copy the relevant adult large piece and paste it into the working area.

  • Replace the 1D piece with the 3D version where needed.

  • Copy the base-color height and use it to replace the side-panel height.

  • Verify the side-panel size.

  • Remember that the back side panel may be larger than the front, so the measurements may not match exactly.

9. Place the technical sketch and base 2D panel together 18:12

  • Confirm that the 1D pieces and other required pieces are placed into the base 2D panel.

  • Add the technical sketch.

  • Break apart the grouped pieces if needed.

  • Bring the bottom binding to the top so it is easy to inspect.

  • You can also bring the front and back panels into view if needed for comparison.

10. Use a contrasting color to spot clipping-mask issues 19:07

  • Hide the base-color clipping mask panel.

  • Drop the binding piece into the clipping mask.

  • Change the color to something obvious, like yellow or green, so any overflow is easy to see.

  • This helps reveal whether any part of the binding is outside the clipping mask.

  • If you see a stroke or edge outside the mask, it means the piece is not fully contained.

11. Final cleanup and result 20:20

  • Move the binding fully inside the clipping mask.

  • Confirm the overflow disappears once it is placed correctly.

  • Repeat for the remaining pieces until everything is clean.

  • Final result: bottom binding is set up for 1D, 2D, and 3D patterns.

  • The process is quick once the clipping masks and extraction workflow are understood.
