For earrings, I have been using an index card.
I fold it in half(lengthwise), and cut it in half(lengthwise) so it will fit in a 2x3 plastic bag.
Then I fold the top of the folded index card about 1/4inch and then then i make 2 small 1/4 inch cuts on the folded area about 1/2 inch from each side of the card.
Then I put my earrings in the slits and put a plastic earwire nut on the back.
Then I put it in the plastic bag, and I type what it is made of and tape it to the top, front of the bag.
Then I put the the bag in an organza bag with my card in it.
I have been putting the price on a tiny rectangular postit adhesive on the inside of the plastic bag. I have been trying to think of some other price tag method other than a string attached to the bracelet because I use alot of wirewor in my pieces and I wouldn't want it to get tangled.
A ribbon may work better because it is not as likely to get tangled.
