Hi Homeschoolmama, I wish I could help but I don't even know what a shawl clasp is. Do you have photos of them in your closet?
Odd question - has anyone seen any pretty uses for shawl clasps? We divided my mother's jewelry up last week, and I inherited two. I do wear shawls, but - how are they worn? I've tried a few ways, and the clasp rolls over.
