I'm running out of different fabrics with which to pair with birds. Each tile is 1" x 1.25", so the birds have to be pretty darn small. Working on rice paper with pen & ink can be tricky, as the paper is very thin and allowing the nib to rest too long on the paper results in a splodge of ink. The metal nib also picks up paper fibers, which can also result in a splodge of ink.
The fabric isn't randomly cut; I select rectangles of pattern that I think will make for good compositions when combined with a bird.
