Whether your pet is a cat, dog, horse or hamster.... If it moults - and virtually all animals do - then its moulted fur can be spun or felted to make a very personal little keepsake or maybe even a very practical garment.
The main problem with pet hair is that most of it is made up of smooth fibres. If you've read the page on sheep's wool then you will know that its fibres have microscopic barbs along their length. When the wool is spun or felted these barbs interlock with those on adjacent fibres so that they grip one another and help hold the yarn or felt together. Without these barbs pet hairs can be too slippery to produce a strong yarn. Unless they are very tightly spun they can slide apart, but tightly spun yarn is hard and stiff. Another issue is that many pets don't provide enough fur to
produce a usable quantity of yarn.
These problems of quality and quantity can both be solved by blending the pet hair with sheep's wool. The wool will provide bulk, and its barbs will help to hold the pet hair in place.
Some beautiful effects can be achieved from such blends, both by using similar or contrasting colours. The ends of the pet hairs will often protrude to give a halo effect. Soft long fur gives best results. Short or stiff hairs tend to work then way out.
