Chiengora

Chiengora is a yarn or wool spun from dog hair. The word is a portmanteau of "chien", the French word for dog, and "angora." It is up to 80% warmer than wool and is not elastic.

Often chiengora is blended with wool during the carding process. This blend has some give to it, which is preferable when knitting. It is also often blended with wool in order to create a yarn with less heat insulation.
