If your Barbie has short length hair, 1 skein will do. Medium to long hair you should purchase 2 skeins to make sure you have enough hair.
1 skein easily rehairs 1.5-2 adult G1 My Little Ponies with regular to long length of hair.
Each skein weighs .4oz OR MORE and is 40" in length. The hair is on a weft, cut approx 5" long, so that if you drop or tangle your hair mid-project you can easily brush it out instead.
Yes, each skein is on approx 5" of weft. I can sell a weft up to approx 40" in length (so if you want 10" of weft, order two of the same color and ADD IN THE ORDER NOTES that you want the wefts together- otherwise we will send two separate skeins). The hair will remain 40" in length no matter the length of the weft.
