Try as we will, we haven't been able to teach sheep to grow continuous filament wool. The individual fibers that make up wool yarn vary from approximately 3 to 5 inches in length and that's pretty much it. As a result, as opposed to yarn made of continuous filament fibers, there are going to be loose fibers along any length of wool yarn resulting in initial shedding of both loop-pile and cut-pile carpets. This shedding manifests itself as little clumps of fiber resembling cotton candy (other than its generally not pink) lying randomly about. Although this can be somewhat disconcerting, the carpet is not coming apart and is not being vacuumed away. It can look like a lot but in actuality, the amount of fiber lost in this manner is minimal. This is the nature of wool carpet and after exposure to foot traffic and regular maintenance, shedding will stop. It may take a while, but it will stop. Honest!
