Bobbins unwinding? Try Bobbin BuddiesTM, the little pink wonders that keep the bobbin thread from coming unwound, even if you drop it. Simply slip the Bobbin BuddyTM over the bobbin, and the thread stays put. Store all of your bobbins in Bobbin BuddiesTM . Especially helpful for rayon, metallic and other slippery threads, but great to have on every bobbin. You'll wonder how you ever managed without them. Sorry, they do not fit Singer Touch & Sew and Athena bobbins. 12 per package.
