I thought I would do a small tutorial on using I-cord to join two knitted fabrics. I could not find anything about this technique in Elizabeth Zimmerman's books, so I un-vented the technique myself. I later learned that Meg Swansen has a demonstration of this on one of her videos. Experience doing applied I-cord to an edge of fabric is helpful.
Tutorial:
Getting ready: Pin the two fabrics together with the amount of ease you need to make the two pieces match.
Perhaps you can see that I am applying a double edging (the pink garter stitch strip with the purple knitted-on lace) to the blanket. The section on the middle left has already been applied with green yarn using I-cord. The upper middle shows the edging pinned to the blanket but not yet applied. There are three stitches on my (sharp points) double pointed needle. This is a three stitch I-cord. I simply cast on three stitches to begin.
Concept: The idea is to generate one stitch from each fabric being joined. In this case, I generated one stitch from the blanket and one stitch from the edging. I obtain easy and good stitches from the blanket, which was knit on the bias, I did a single crochet in the green yarn all the way around the blanket, doing one single crochet stitch in each garter stitch "valley" row.
STEP THREE:
Put this new stitch on the right side of your working needle and knit it together with the second stitch (previously the first stitch) on the needle.
Do the same idea for the blanket edge. You have already knit the first (new) and second stitch on your needle together. You then knit the middle stitch of the I-cord on the needle. Then, you slip the third I-cord stitch.
Put your left needle under both loops of the single crochet edge of the blanket. Pull the working yarn through these loops so that you have one strand of yarn on the left needle as a fourth stitch. Put this stitch on the right needle.
STEP FIVE:
Pass the slipped (third) stitch over the new stitch. Slide the stitches to the other end of the needle and repeat from the top.
