This gal is getting her hair first and here's how it is going down...
First I pinned and sewed short bags and a base of hair around her head.
Then I wrapped the yarn around cardstock and sewed down the middle. I try my best to keep it evenly spaced but it inevitably bunches up. It doesn't make much of a difference.
Then I fold a bunch of times on the stitch line, tear apart the cardstock and remove and I have a strings of yarn loops to sew to my doll's head for curls.
I pinned them in place, wrapping around the crown of the head. Now I need to go sew them down.
