Here is a toddler-sized leg warmer. Puddin's leg is too skinny, but you get the idea.
I just cast on 28 stitches,
worked k2,p2 around for 8 rows,
knit around until long enough,
& finished with a matching rib at the other end.
The yarn is Caron Simply Soft with size 8 dpn.
Same deal with these baby-sized legwarmers. "Cast on 24" and "stop sooner" are the only differences. For full scrunchie up the calf effect, these fit nb-12mo. And, no, Trixie wasn't happy with this modeling gig.
