Browsing forums is a dangerous business. Reading the latest on cross-stitching.com, I encounted yet more posts about something that keeps coming out - ATCs.
ATCs - or Artist Trading Cards - are collectable cards the same size as regular trading cards (think Pokemon and Doctor Who) made by an artist and can use just about every media out there. The ones on cross-stitching.com have cross stitch (well duh!)
It's something that I find absolutely fascinating. I like making cards and other papercrafts, so I think this is a natural offshoot of that. I've also been looking at altered books and there's a book about artist journals on Amazon that I'm going to buy just as soon as I can afford it.
