Well ruffling is really easy! The way I do it is pick up and knit the stitches on the edge, wherever you want your ruffles, then purl on the wrong side. Then on the RS just do (K1, inc1) the whole way through. Purl the wrong side. Do the same (K1, inc1) on the right side one more time, and then you can either purl the wrong side again and bind off or just bind off on the wrong side. I did the latter because I was running out of yarn. Hope that makes sense!
