Button Floozies

Is it just me, or do those tiny white buttons just multiply like crazy in your collections, too? I really do like them, but they always outnumber the larger, more unusual buttons in any bags or jars I buy. That's why I was excited about putting a good number of them to use in this mosaic birdhouse. It was gratifying! It feels very wrong to throw a button out, even a tiny white one. Any other ideas on how to use these little puppies up before they take over completely?!
