I originally designed this quick knit Cup Cuddler as a PDF knitting pattern. It is seamed, pieced, and blocked. I recommend cotton yarn for a cold beverage Cup Cuddler and a wool/wool blend yarn for a hot beverage Cup Cuddler. It's a great pattern for using up those bits of yarn in your left over stash beause it only requires approximately 20-25 yards of yarn in a worsted weight.
Skill level is some experience needed.
