In the upper left is transparent acrylic, 1/16" thick. The engraving on the surface is much more visible in real life, but it can be emphasized by applying a very thin wash of acrylic paint and then wiping off the excess. This is what I did for the tool in the lower left, which is black 1/16" acrylic.
On the right is a 1/8" plywood tool. The engraving is much more visible, and this tool has the improved cutout shape to fit around some figures more easily.
