In the meantime, I had to check out the Cricut stamping goodies. Now you can cut acrylic sheets and make clear acrylic stamps for rubber stamping!! I am a bigger fan of rubber stamping than I am of actual die cuts made by the Cricut, and that's probably because I am a not a huge scrapbooker. I do love stamping though, even if I'm still new at it!
So, while this is not a tutorial, you really don't need one. Simply buy the Acrylic sheets (and blocks if you want, or you can just buy regular acrylic blocks) and get rolling! You do need a deep cut blade and it's best if you start with a fresh mat. I get most of my supplies from Oh My Crafts.
Here is a few stampings I did with cuts from my Cricut!! What you stamp will vary on what cartridges you have!
It took some practice getting the hang of smooth stamping but this looks like it's going to be really fun. It seems you'll probably have some trial and error in deciding what cuts would make the best stamps, but this is my fave part of the Cricut so far!
