Just three straight stitches intersecting make up each eye; a small piece of felt with one small stitch is the mouth. That one stitch keeps the mouth on and divides it into lips.
So simple and so nice!
The hair looks like layers of recycled pieces of knit with straight stitches here and there to keep it in place. I really like that.
When I got home today after taking these pictures, I found this photo of some other dolls from the same maker.
