Q ~ Why add a Fill/Outline/Border/Background?
A ~ For some sizes and materials, this is required in order to be able to print/cut the design
When optional, fills/outline/borders/backgrounds, can provide contrast between the design and the fabric or item being applied onto. Backgrounds can also make applying transfers easier if the design has multiple small pieces, or for stickers, so small pieces won't come off on objects that are handled frequently; be used to make a reverse 3D effect or add a large pop of color with a solid color or pattern.
Q ~ What is an overlay?
A ~ Overlays are transparent patterns than can be added over the top of a solid color or ombre pattern, creating your own unique look. Our Buffalo plaid is an example of a black overlay over a solid color.
