I like using either fabric, high-quality specialty yarn, or natural animal hair on my dolls. Here are my favorites:
Natural mohair locks – Using a felting needle, loose locks can be rooted directly into the head of a cloth doll. They can also be glued onto a clay doll.
Tibetan lamb hair – Comes on the skin, and can be sewn into a wig or glued onto the head in pieces.
Yarn fiber – Oh the sky is the limit with this! Of course, yarn is perfect for funky cloth dolls. Root the fiber in just like mohair locks.
Fabric – This can be a lot of fun. Cut scraps into ribbons form random hair, or use trapunto to “applique” patches right onto the head of a cloth doll. It can be incredibly creative.
Feather Boa – Fairly easy to find in any craft store. Wrap it around the doll’s head for a fast funky look. Glue in place using a clear glue like Fabric-Tac.
There are many other types of fibers on the market, and I do love to experiment!
