I am participating in an artist trading card swap over at Creative Coach Space. We're making 2 standard sized artist trading cards which are 2 1/2 x 3 1/2 and then one that is 2x2 and one that is 1x1. I know I'll be getting out my magnifiers and tweezers for the tiny ones. Here is one of my "official" sized artist trading cards. I started out by trying to sew through cardboard with embroidery thread but didn't get too far when I set the needle through my thumb. So much for thimbles that don't fit your fingers. Still, it was fun.
