Create your own stamps! Just open an empty canvas with transparet background, create a shape, a letter, a word... Whatever. No matter what color it is, but it must be just one layer (delete de background one). Then play the action and... that's all! You'll be asked for the color so don't worry about it :)
The action must work in any language Photoshop, but if you find errors, please contact me.
There is a bug, founded by Blue Cat (Thanks!), the actions creates a layer for the inner stroke, each photoshop lenguage rename this layout, and my photoshop uses the spanish expression. I'll try to fix it and re-upload.
Fixed! Please, re-download :)
