    Where can I find good quality pin backs for brooches?

    I've tried the pin back brand from Michaels and I've also tried Darice from Joann. The pin part of the Michaels brand was too loose, and about half of the package of Darice ones weren't functional due to poor alignment or the clasp was stuck in place. Does anyone know from experience, any brands...
