|At the end of the row, cast on four stitches to the left knitting needle. Knit the first three I-cord stitches, and then work an skp decrease, joining the last I-cord stitch with the first stitch of the main fabric. Repeat until all the stitches across the main fabric have been bound off. To turn the corner, work three rows of unattached I-cord. To attach the i-cord along the vertical edge knit three, slip one knit-wise, knit one stitch from the main fabric edge, and pass the slipped stitch over. Repeat.
