This is my favorite for the day. These _____ cards have little punch holes in a white foreground with the backing available in a variety of colors so you can create your own greeting cards. Check out the website where you can pop out the punches and create your own design. I will update the post when I find out where to buy these. I'm also trying to figure out who exactly makes them... looks like some company named breed. Whatever. Cool concept.
Check out the Flickr group for other peoples' creations.
The link to buy the cards works now. $10 plus shipping gets you 5 cards in the colors pictured above. Go here.
