Create sweaters, throws and more with Red Heart Super Saver Jumbo Yarn. This large size yarn is ideal for larger projects. Red Heart yarn is made from acrylic materials. No-dye-lot solids and coordinating multis make match colors easy. The larger skein sizes make it easy to weave in fewer ends. With more material to work with, if you end up needing more yarn than you anticipated, it's not the end of the world, just the end of that acrylic yarn skein. The yarn has a medium/worsted weight and can be machine washed and dried, making it ideal for bedding and garment making. It can be used for a variety of applications, including crocheting and knitting. The yarn works easily with a I-9 (5.5mm) crocheting hook with a crochet gauge of 12sc x 15r = 4 inch (10cm). It can also be used with a US 8 (5mm) knitting needle. Choose from multiple colors.
