I'll start. Here's a little set of bird cards I just did: (These cards are not available for trade.)
The color is a tad off (the paper they're on is really white), but it's not too bad a representation. I've been really enjoying working with birds lately. They're so fun. Plus, I have a huge book of Audubon prints that I got at a used book sale for $1.00, so I have tons of birds to work with!
