This was the first BO method I learned when I was new to knitting. It’s not a bad choice for beginners because it’s really easy to learn and it’s not too shabby looking. Unfortunately, the rest of my knitting skills advances and I kept using the same old BO.
I’m rather fond of the Chain BO, even if it doesn’t usually work for what I’m doing. I like the crisp line it makes at the edge and I like how the bottom of it looks like a line of stitches or a crocheted chain. I love that you can crochet right off the edge with ease.
The Chain Bind Off definitely has it’s place in knitting, but it doesn’t even begin to qualify as a stretchy BO method. It’s difficult to bind off loosely and it doesn’t stretch much even if you do. It can be quite rigid feeling when you try to stretch it. My swatch only stretched from 2 inches to 3.75 inches. That’s just not enough stretch for ribbing so I’m on a quest for a new BO method.
