Slip a mesh sleeve over cakes, balls, or center‑pull skeins to prevent tangles and collapsing edges as you knit. This set includes two 12.5 cm, two 17.75 cm, and one 25 cm sleeves to cover common yarn sizes from lace to bulky. Reusable and lightweight, they keep yarn tidy in bags and baskets and reduce snagging from label edges or zipper pulls.
