Little Shop, Little Shop of Notions
Thrift shops can be good sources of inexpensive, hard-to-find fabrics and trims. You can sometimes find buttons (especially mother-of-pearls), necktie interfacings, bra underwires, fur trims, and other interesting notions on relatively cheap garments. After I've taken the buttons or other trims off, I sew on replacements and donate the clothes back to the shop. No applause necessary.
