The best part about this vest is, the pattern was designed for real women! So if you'll stop by Laylock you can see the beautiful vest she made and get all her tips and instructions. I sincerely thank her for this great schematic that makes this pattern as easy as pie:@)
Knit Outerwear Barbie Vest-Faux Down or Faux Fur-adapted from Coze: Easy Knit Vest Pattern
10MM needles, worsted weight or fuzzyyarn, all garter stitch.
Back: cast on 10, knit stitch until it reaches just under where Barbie's shoulder meets her arm. Approx 14 rows. Bind off.
Sides: cast on 7, knit stitch until it reaches from the bottom of the back, wraps around the back of her neck, and down the other side to the bottom of the back. (Wrap it around her neck like a scarf.) Bind off.
Finish: Sew sides to the back (up approx 1" from bottom of vest) leaving an opening big enough for an arm on each side. Then center the collar and sew it to the back all the way across the top of the square.
Note: If you use a thinner yarn you'll be able to fold the collar down like Laylock did, this thick/fuzzy yarn is too bulky for that.
