This was our advanced class project for July. The idea and a tutorial can be found on the splitcoaststampers resource page.
This is quite a technical piece and I had a few attempts before I got it right. This did mean that I knew the pitfalls and was able to ensure the class ran fairly smoothly with only a few mistakes being made and those easily rectified. Btw, if you ever need to unstick something a quick blast with a heat gun softens the glue and allows you to remove the stuck piece. ... Go on, ask how I know?..... Lol
