I ran out of toggles! and I'm in a cheap mood, so what could I use? Buttons!! I found a great source for vintage buttons at a great price and I bought a few. Add a beaded loop and voila! a one-of-a-kind clasp for my necklaces. The button is vintage Czech slag glass. In natural light, it matches the vintage Lucite beads. I bought some really super buttons for other necklaces- enameled, with Swarovski rhinestones and cabochons, transfer patterns on porcelain (like on dishes), oh I could have spent a fortune there; fortunately I didn't ;^D.
