An applied i-cord is one that is knit on rather than sewn on.
Using double-point needle, CO 3 sts.
[I]Next Row[/I] [RS]: K2, sl 1, use tip of leftt needle to pick up a st in edge of work, k this st, pass slipped st over. Slide 3 sts just worked to other end of needle and bring yarn around back of work, ready to begin working the next row.
Repeat this row for Applied I-Cord.
To be honest, I think that this way is a bit more complicated than it needs to be.
When I add an applied i-cord, I pick up stitches all around the edge that I’m working.
Then, knit 3 and slip them back to the left tip.
Knit 2, ssk (the last stitch of the original 3 and the next stitch on the left needle.)
Slide the 3 back to the left tip and keep repeating until you’ve run out of stitches. Then you can sew the end on to secure it.
