Red Heart Super Saver Jumbo is exactly like our trusted and loved Super Saver yarn, but in a bigger ball. No more having to connect skein after skein while working on projects, with each ball having around 2 times the amount of the normal super saver skein. We have no dye lot solids for Super Saver with each ball approximately 744 yards in length. Prints, multi-colors and heathers are approximately 482 yards in length. We recommend a size US 8 knitting needle and a size I-9 crochet hook for this size 4 medium weight yarn. You can machine wash on warm; tumble dry on low.
