Double Ribbing is knitting on every needle on both beds. Verses 1X1 ribbing where you use every other needle.
English Ribbing (or Half Fisherman's Rib is tucking in one direction on one of the beds. Doesn't matter if it's the main bed or the ribber. This is what I did for the scarf. I can directionally tuck if I use my ribber on my Studio 155. I might be able to tuck with the main bed, but I'll need to experiment with the stitch dial. I've been told it can't be done.
Fisherman's Ribbing is tucking in opposite directions on both beds.
When I was confounding my friends with my ribbing questions they both suggested I just make a 2X2 ribbed scarf. Though lovely in it's own right the English Ribbed scarf I made is so thick, soft and luscious comes to mind. So, thick, soft and luscious that I don't want to give it away!
I used Red Heart Medley in the Urban color. The scarf is all washed up and ready to be wrapped. Every time I walk by it I pick it up and bury my face in it. It's so soft and warm and smells so good. If it wasn't going to my daughter I might have had to wash it again.
