This week I learned how to make my own copper toggle clasps. This steel block and old ball-peen hammer are my favorite tools right now. The other pair of plier-looking things is a bail maker.
Toggle clasps are the interlocking connectors I like to use in place of those hard-to-manage ring clasps.
Bails are the big loopy loops at the tops of the pendants you can see in the Lost Marbles Jewelry shop.
