Of course you knew that I would choose Beads for my B-word. I am in love with those small, and sometimes not so small, pieces of glass!
I love that I can take tiny pices of glass less than 2mm in size and make almost anything out of them. Of course there's the requisite jewelry, but I have also made boxes, butterflies, bookmarks, keychains, candle-holders, dragons, many species of fish, and much more. I have weaved small beads together so that they made a bigger bead, a "beaded bead".
Once, just to see if I could do it, I even beaded a push-pin!
Don't set anything down in front of an avid beader, for you may return to find it covered with beads!
