I made a set of 3 TC, each was different just because that's the way they evolved. On the last card, I punched a hole with my eyelete setter (biggest punch) through the first two layers, the white and purple, and glued the eyes on the black layer. It's a nicer look than just glueing it directly on the white layer.
In the middle card, I punched a hole in the middle of each little star exposing the purple layer.
