No one is permitted any longer to refer to their knitting projects with gendered pronouns.
Even if the hairs in the wool actually contained chromosomes (which I don't think they do), the wool is not a gendered organism. The yarn is even less gendered if it's not wool. And a sweater, even if the pattern is named "Annabelle" or "Mickey" or "Juliette" or "Steve", is not gendered either. It's an inanimate object, it's not even a vehicle, it's it, not she or he. Just deal with it.
