Maybe you can find a used one?
My DGD just spent the night last night - we made Barbie clothes out of socks. She has so much trouble seeing and sewing tiny things... I google searched and found Barbie clothes made out of socks. We had a BLAST cutting up socks and putting holes in them. I doubt if we made permanent clothes but Barbie isn't naked any more - she's fairly modest - DGD had a lot of fun and now she can do something herself. Then since we didn't use up the cut up odd pieces of my stash, we sewed 3 blocks for a crazy quilt. She was ssoooo excited. Trying to match corners for her is a trial so this will be a good way for her to make her own quilt.
