white is same as your other post - the teeth will be yellow or a hole without a white back layer
I'm on the fence how to lay this out - with only two layers yellow has to go on top which will be thin outline around the letters and the separate yellow parts will be 3 pieces or slightly modified to bridge them together
if you can go with more layers I think it would look good - it will add some nice depth - and be easier to assemble - except the white will be puzzle pieces on the same layer as purple and then you won't need a white back layer
