There are a lot of things that I'd like to do some day...and I just found another thing to add to my list. From Geninne's blog, I just found her tutorial on how to make hand-carved stamps.
Visit Geninne's Art Blog for more on the tutorial/how-tos. She shows you what she uses to make the stamps and more.
And, here's another post from another artist, Margaret Oomen who learned Geninne's stamp carving and makes beautiful stamps among other things!
