Enameled Head Pins

I made some enameled head pins last night, and had a great time! I listed a set in my SueBeads etsy store. They were made on 20 gauge copper wire. These ones measure 2 inches. I made some more this morning that measure approx. 2 1/2 inches. These ones would look great paired with ceramic beads, or lampwork! I had no idea what to charge for them, so they are 20 for $4.00 right now. If anyone has a better idea, I am open to suggestions! Or, if you want more, or less, or whatever, let me know what your opinion is! I have thrown them, banged them and squeezed them and the enamel does not break off!
