I've done so many things with I-cord. Haven't we all? It's good for edgings, trims, drawstrings, handles, and straps. I've been fascinated for a while by variations on I-cord, and this video is a small example of that.
You can use you a little of your excess stash by making gift wrap bags and ties that you can reuse. It saves money and reduces trash!
Knitted cords often are much better than the fuzzy yarn ties you can purchase. Cord knitted with sturdy yarn will hold up a long, long time. For fun, you can mix different strands, colors, textures, and even add shiny run-along yarn. In the video, I used the patterning system on the machine to make a candy-cane type of stripe.
