After making Mom’s Ribwarmer I charged ahead into making one for Nikolai. I gauge-ed it down to kid size and did a one piece back, but everything else was strictly by the book. Alas…. The Ribwarmer, it seems, was designed for adults whose shoulders are broader than their tummies. My dear gangly 4 YO’s Ribwarmer ended tight around his belly, with shoulders wider than the 80s. Oh well. Rather than start all over I did a crochet steek (my first, but definately not the last) to narrow the shoulders from 20 sts to 12 sts. I wasn’t sure how a crochet steek would work on garter stitch, but it was pretty painless and turned out very well.
So- PSA for those of you making Ribwarmers for young kids: try this more anatomically appropriate version. After you have knitted your 10 ridges on 10 sts, cast on 12 (not 20) and then increase 1 stitch on the short (armpit) side every 5th ridge down to the first miter. You should end with 40 ridges and 30 sts. On the backs do the same thing- after you’ve finished the miter knit 3 ridges then start decreasing 1 stitch (still on the armpit side) every 4th ridge. You should end with 35 ridges and 22 sts. Then finish off as EZ instructs.
