Plarn plastic yarn made with garbage bags. I cut and looped the bags, double stranded for strength about an inch thick. I recommend using a J hook or larger. Because pieces are knotted pulling tightly can cause tearing if that happens just re- tie. This material is excellent for weaving too. Purple ball is 107 yards, gray 120 yards, white 113 yards. Prices are for one ball please specify color choice or I can make any color made to order. Variegated balls are a great choice to add patterns to your work.
