Ribbon Scarf Pattern
I have knitted several sideways scarves and the problem I run into is that one edge is more stretchy than the other and without violent blocking the scarf will take a cork screw shape.
Beginning and Ending:
To begin this scarf single crochet 200 stitches and knit into those, picking up two of the three loops of the crochet stitch. To finish the scarf bind off with a smaller sized crochet hook (about 2 sizes smaller).
After you have the 200 crochet stitches established begin the body using US size 7 needles. You will need circular needles that are at least 32 inches long to accommodate the amount of stitches. Knit 3 rows. On the 4th row K1, YO3 to the end. On the 5th row drop all the YOs and knit each stitch. Repeat as many times as you want to. On my scarf I repeated 4 more times (a total of 5 repeats).
Wash, and pin. At this point weave in the ribbon. It's a bit of a pain to weave the ribbon in when the scarf is pinned, but this way you ensure that the tension of the ribbon works with the scarf. I made a knot at both ends of the scarf with the ribbon to help keep it in place. Occasionally the scarf will snag on something. Just hold the section taught and tug horizontally and vertically until the yarn has worked its way back into place.
Check here for the yarns I used. The brown yarn is an alpaca/wool blend called Valparaiso. The beautiful ribbon is Zingaro (color 1, I think). Both are from ArtFibers in SF.
