I have a new PSP script pack in the store(s).
In this pack you find 3 PSP scripts. Each script creates a sticker effect to your element. The scripts crops the finished element, so the element has to be single layered. The first script creates a thin (10 px.) sticker, the second also creates a thin (10 px. sticker) but this one has a 3D effect applied, and the third creates a thick (30 px) sticker.
