My rectangle was bigger then most as I had added an extra pattern repeat to each sleeve, to be certain that the sleeve would fall past my elbow. I decided to do sixteen pattern repeats, instead of the thirteen repeats called for in the pattern. I like positive ease in sleeves.
When it came time to connect the sides of the sleeves using a three needle bind off, I balked at first. I prefer the smoothness of the kitchener stitch to the seam created by a three needle bind off. But after reading through the directions, yet again, I decided to follow the pattern and do the three needle bind off. The beauty of the three needle bind off is that you do not have to cut the yarn. You seam the sleeve and then continue knitting across the stitches. Seam the other sleeve and suddenly you are knitting in the round. Creating a sweater in one brushstroke or one unending piece of string.
