I nominated Knitting (Anthropomorphic) with different yarns as characters.
"Handspun wool yarn" is a description of a type of yarn; the other 5 are specific yarns. Here are their listings on Ravelry. (The name on Ravelry is always the longest version of the name, so there are some discrepancies between the common names that I used and the titles of the pages; but if you look at the photos, those all match the names I used.)
