How to layer vinyl without overlapping colours
A layered decal usually stacks: the bottom colour is cut whole and the others sit on top. You can also cut each colour only where it shows, so nothing overlaps. Both are right; they suit different projects.
Short answer
To layer vinyl without overlapping, cut each colour only where it shows: the bottom colour is cut with holes where the other colours go, and those pieces drop into the holes edge to edge (sometimes called a knockout). It uses less vinyl and stays flat, which helps on iron-on, but every edge must line up. If the colours in your design don’t touch, stacking and not overlapping come out the same.

Two ways to layer the same picture
Stacked. The bottom colour is one whole piece; the colours above sit on top of it. Small misalignments don’t show, because there is colour underneath. The cost is extra vinyl under the top layers and a thicker spot wherever they overlap.
Side by side. Each colour is cut only where it shows. Nothing overlaps, so the decal is one layer thick everywhere and uses less vinyl. The cost is precision: any gap between pieces shows the surface underneath.
When to choose which
| Project | Usually better | Why |
|---|---|---|
| Iron-on with many colours | Side by side | Fewer stacked layers stay softer and press more evenly |
| Adhesive vinyl decal, first try | Stacked | Forgives small alignment errors |
| Expensive or specialty vinyl on top | Side by side | Cuts only the area that shows |
| Fine details on a solid shape | Stacked | Details sit on the base instead of needing holes cut around them |
Doing it from a picture
In Decaly the choice is the Layering switch on the trace screen: Stacked or Side by side. The trace stays the same; only the way the layers are cut changes, and the screen says what that means for your picture, for example “Each colour is cut only where it shows, so the pieces meet edge to edge and use less vinyl.”
Stacked in Decaly is careful about what a colour runs under: a colour only underlies the shapes it actually touches. In a lettering piece where two words in different colours never touch, both choices cut the same, and the app says so.
Getting the edges to meet
- Apply the largest piece first and use it as the guide for the others.
- Keep each layer on its transfer tape until it is aligned, and look for one shared feature (an eye, a letter edge) to line up by.
- Avoid side by side for hairline gaps between colours: a sliver of vinyl between two neighbours can end up too thin to weed.
