Maybe it was those little post-it note squares, but now I'm having fun coloring on a different little square: the coaster. Have recently decided I don't like business cards (I never hand them out and rarely keep the ones I get) but want to have something to send out with my art when purchased. First I had coasters printed (with my art) and I do love them, but small run coasters are not cheap. Then I discovered with a little experimentation that you can buy blanks and paint on them! So now each order comes with another little hand made piece that is also useful! I love multi-tasking products.
