Whenever I go into a bead or fabric store I always look for a brooch base. Its easy to find them on-line but I never see them in stores. I finally found some at McNare Beads here in Ottawa and bought a bunch. Basically you use glue to add stuff to the base. I'm hoping that this style will sit better on a shirt. I hate it when they tilt forward, the brooch looks like its trying to jump off your chest!
