I also have loads of shrink plastic and have been meaning to try some different techniques. I went to the Lucky Squirrel website and drooled over several samples of amazing art. I decided to try the intaglio technique. I punched out circles with my Marvy 2 1/2" punch, punched a hole to attach it later and then shrunk them. Once they are shrunk, you super heat it with a heat gun until it is soft. Then you impress a stamp into it and it leaves, well, an impression. You can do this with an inked or uninked stamp. In this case I chose to ink my stamp in silver Brilliance ink first because I thought it would show up better in the black shrink plastic. I sprayed it with a glossy sealer and then used a silver Krylon leafing pen on the edges. They are attached to the silver bracelet with O rings. I think they kinda have an Asian look to them. Oh yeah, the stamp I used was the outline stamp from the Flowers for a Friend set.
There is lots of inspiration out there....such a wonderful world we live in!!
