Cheap Clamps

Clover clamps, historically known as "bird clamps", for their shape, function as an extra hand for clamping fabric. They're usually packaged with a large C-clamp, and known as a "clamp and bird set", so they can be attached to a sewing table. Oddly enough, they're made by Clover, so they really are "Clover Clamps". (Thanks go to crymsin_lilly on FetLife for the link.)
