Bethany liked her Some Cloudy Day legwarmers in Malabrigo Mecha so much that she decided to make a baby-sized pair for Penne with her yarn leftovers! She cast on 20 sts and worked in 2x2 ribbing in the round on US size 9 dpns for about 1'. Then she increased to 21 sts and switched to stockinette stitch for the remainder of the legwarmers, about 5'. She just measured Penne's calves and stopped when they were long enough. Bethany knits at a loose gauge, so to obtain a similar gauge as her, you would want to us a larger needle--approximately a US 10.5. These turned out super cute...or maybe it's just the baby. Either way, we love them!
