I used a worsted weight yarn from Knit Picks and 10.5 circular needles.
CO 60 stitches and join to work in the round.
K2, P2 several rounds to make 1″ to 1.5″ ribbing.
Switch to stockinette stitch for as long as it takes!
Add stripes to make it more interesting.
When you reach the desired length, bind off and then stitch together.
Fun and cushy!
