I saw this technique over on Annette Quirke's blog a few weeks ago and knew it was something I HAD to do! She has an amazing collection of her own carved stamps - and they're so colorful from much loving use - they look like candy.
This is what I needed to give it a try. I already had the Speedball cutter - and the erasers were found in the stationery department of my grocery store. Gotta love that! Geninne's Art Blog has a great tutorial if you're interested in trying it too!
