Here's a few ideas, of course my buttons are mostly old ones except for figural which I will use as tiny garden additions...see old scrap block. I can't find my finished blocks but picking out buttons for them is fun! Do not use the hard plastic ones on something you're going to put in the W&D. I started off putting big buttons on corners where it wasn't matched up square. I recently made a Sunbonnet girl redwork w/old red buttons (all different) but squares were near perfect but gave a nice look to it. Younger girls like to make bracelets on elastic thread.
