This template is a Coaster sized model, that you can insert 1.75mm end pieces of leftover filament into. Create your own patterns. This model was created to use leftover PLA filament pieces, in order to reduce waste. After the pieces are inserted, you can leave as is or use an Iron or Heat Press (I used a Cricut Heat Press) to fuse the colours. Some of the waste filament "Pixel Art" is better not melted as it can lose some details on smaller templates.
