I found a darling little stamp store - Stamp it Rich! - in Placerville, CA this past weekend. The card samples were amazing using some techniques that I'd never seen. I probably could have started a whole new hobby if I stayed there much longer - LOL. I did buy a stamp and then visited the manufacturer's website. You really should take a look at their gallery - there are some fantastic samples. Here's the site: http://www.outlinesrubberstamp.com/. I've bookmarked the site and plan to try some of the techniques.
Hugs and Happy Crafting,
