Here is what I started with:
A piece of this stuff, cut wide enough to fit in my Xyron Machine
StazOn Ink in Black
Acrylic BlockStamps to work with
FIRST (and very IMPORTANT!) peel the clear film off the backing sheet and flip it over. Through some experimentation I found one side of this clings to a block better than the other side. Don't make the mistake I did and stamp on the wrong side! Stamp your images with StazOn on the clear film, leaving enough room around the images to accomodate the rubber of the stamp. I use a pad under my paper (or in this case, film) to get a nice clear image.
Peel off the clear film and feed it through your Xyron machine, like so, with the stamped side up:
When you're done, cut them apart and then trim them down so the edges are nice and tidy, (this is before the final trimming):
The cling film sticks perfectly to the CD cases and acrylic blocks!
Thanks for looking!
Cheers!
