If you have necklaces you can always do with something to hang them up, as e.g. the mini dress-form jewelry stand.
That’s something you can use the wonderful bust for.
But it is also something very special if you want to sell jewelry.
Incidentally I think that you can craft it a little smaller if you need a gift wrap or sales wrapping for your necklace.
If the bust is made as greeting card the necklace can directly be send with it!?
If you make such a bust I’d really appreciate a comment with a link (as I’m glad about every comment ;-))
