This is really my first time working with rib knit. It's a little bit more fluid-like and can stretch beyond necessary if one isn't careful. I adjusted my serger's differential feed to help and I also used a Walking Foot for the top stitching. The Walking Foot made a world of difference - WOW!
I think lettuce-edging is sweet and feminine... and one advantage to rib knit is that it ends up more ruffly than other knits using the same technique - perfect for finishing little jammies like these. I set my serger to a rolled hem and following the steps in my instruction manual, I achieved a frilly edge. I believe the knit is a Baby Lulu print and I totally love it. Would you believe I eeked this outfit out within one yard! it was nip and tuck, but I *barely* got it. I think it helped that this particular Ottobre pattern runs slim. Pattern was from the 04/04 issue - both the top and pants in a size 110 (5-6).
