I did a lot of experimenting with applied i-cord when I was designing the Ruby hoodie. Because the i-cord is a contrasting colour to the hood, I wanted to make sure the other colour wasn’t poking through the i-cord when it was complete. Most of the ones I tried were messy. I finally found the one I was happy with; it neatly encases the selvedge edge inside the i-cord tube.
Start the same way you would for a regular i-cord. Using a double-pointed needle, cast on 4 stitches.
Slide the stitches to the end of the needle so that the first cast-on stitch is ready to be knit.
With the working yarn coming from the fourth stitch on the needle and stretching behind the work, insert another double-pointed needle into the first stitch and knit.
(The next few photos show the i-cord already attached to the selvedge, but the principle is the same.) Knit to the last stitch.
Slip the fourth stitch as if to knit.
Yarn over by bringing the working yarn to the front of the work.
To attach the i-cord to the selvedge insert the knitting needle into the space between the selvedge stitch and the next stitch in that same row …
… yarn around the needle and pull a loop through the selvedge as if to knit.
This is usually called “pick up and knit” in most knitting patterns. For the Ruby hoody, you’ll be picking up a stitch every other row on the hoodie selvedge.
You now have 6 stitches on your needle—it’s time to get rid of 2 stitches.
Pass the ‘yarn over’ stitch over the ‘pick up & knit’ stitch.
Then pass the slip stitch over the ‘pick up & knit stitch.’
You now have four stitches on the needle and you’re ready to start over. Repeat Steps 2 through 8 until your applied i-cord is the length you need.
