Susan's Scarf by Gretchen Tracy
This pattern can be found here:
Notes: The finished scarf was 152 cms in length x 17 cms on width. I used the size 11 needles for long-tail cast on, the black stripes, which were a knit front and back stitch, then half those stitches were placed on a provisional piece of yarn, then chain-stitched with a crochet hook. The remaining stitches were changed to a size 10.75 needle, then continued knitting into the main body of the work in white, then the same black stripe, and again on the ribbing. The ribbing used a size 10 needle, and the center panel in stockinette used a 10.75. The final rows of black were knit one row with size 11 needles, then cast off on wrong side. It was much trickier to accommodate the color changes and make them look the same than to do the pattern in one color. All four black stripes were different.
