After knitting through many troubles, I finally completed the longies from Yarn Pirate yarn. They've gone to their new baby owner and I hope they keep baby dry and warm next winter.
I originally knit the legs in the multi-colour yarn, and then switched to brown when that ran out. But then I had longies with cuffs that came above the knees, and that looked just plain dweeby. So I knit the legs by alternating colourful with brown yarn, with made the legs look much better, and I still had enough brown left for a 3-row cuff. The longies came out about an inch and a half shorter than I'd hoped.
