A while ago I bought a shrink plastic set with black, white, clear and translucent papers. And more recently I bought a dvd with instructions, so I thought I'll give it a try.
The small firefly is already shrunken, and was stamped with black StazOn on the white plastic. Painted it with ProMarkers on the stamped side.
The ruler and the other firefly is made on translucent plastic, the ruler is hand-written with a permanent pen and already shrunken here. This firefly is stamped like the other, but painted on the back.
Since the translucent one lost its transparency after shrinking, I added some stickles on the wings.
I also made a heart on the black plastic by stamping with platinum StazOn, but didn't take a picture of it since it was a present for my husband.
