I just recently discovered Waltzing Mouse Stamps and I have to say they are brilliant! Today I decided to participate in one of their challenges where you had to follow a sketch and use at least one of their stamps.
Just got a whole lot of new stamps from a brilliant place called the Stamp Smith. This is the image that I first saw on Docraft and really liked. I asked the friend who has used it in an ATC, where she got it. Well she borrowed it from a friend who got it from ebay as a one off. But.... it had a title. I googled the title, and hey presto found the site. They have great stamps and offer a really friendly fast service. I highly recommend them!
