Most of my dolls have raw edges. Although I fuse the fabrics to interfacing to prevent unravelling, I still wanted a cleaner finish so I thought I'd attempt a blanket stitch around the edges. I was very careful to make the stitches as even and neat as possible and I used cotton embroidery floss vs regular thread.
You know what? I really like the result. I'm going to be doing this all the time now. Makes for an extra step, but it's well worth it. There's something very relaxing about hand stitching.
