An easy way to embellish the edge of any project: add an i-cord!
Essentially, it’s a 3/4-stitch tube you’ll knit onto the project as you go. This video outlines how to do just that when you’ve already completed your bind off, or you want to add it along a perpendicular edge of your project. (Ooh! That just gave me an idea for the sweater I’m working on!)
You can also use this as a bind-off technique if you like, but instead of picking up a stitch, you’ll just include the next stitch in the bind-off row. Stay tuned for a video on that!
