One of the great things about Waldorf style dolls is that they can be repaired or restored. If you have a doll whose hair got matted or all loved up from lots of play time you may want to replace the hair.
In order to do this the top layer of the wig must be carefully removed stitch by stitch. You can use a seamripper or small pair of sharp scissors. If the wig underneath is still in good shape you can leave it on. But maybe you want an entirely new hair color. You could change the doll's hair completely if you wanted to. In that case you could remove the entire wig and make a new one.
The doll you see in the pictures is little Zoe. She recently came for a visit to get a Spa treatment in my studio. Doesn't she looke like new after she got the new hair do?
