I came across a non roll edge in Knitting Machine News and Views. I just used a bulky yarn to see how this would turn out. On the side that you want your non roll edge, just pull out 2,3,or 4 stitches at the edge to hold position. Take a separate piece of yarn and e wrap those needles and knit one row. Then reverse e wrap those same stitches going back. Continue e wrapping for entire length. This might not be new to a lot of you but what I noticed when I was done was the really nice spaces if you wanted to crochet your edge . The e wrapping gives it stability and prevents curling of the edge if you do too many crochets on an edge without this technique. I crocheted a row and chained three for a buttonhole. Then I chained a second row. This is an ideal way to do a band especially if you don’t have a ribber.
Of course, if you are using the passap you would e wrap but not put the needles to hold.
