You just finished your dream project to realize your bind-off is too tight, and it is pulling your knitting. Let me tell you a little secret and easy way to create a loser bind-off edge: use a larger knitting needle to work the bind-off!
Going up a needle size to bind off will give your last row a much-needed stretch. What a simple trick that creates a big difference, right? This is how you do it:
1- Once you get to the point where you need to bind off, bring in a larger needle. I usually go up one size, but many knitters go up to two sizes. I like to go up just one size because I know I will not be creating a flare.
2- Hold on your left hand the needle you used for your project with all your stitches and the empty larger needle on your right hand.
3- Bind off normally. Remember that I love this technique to neatly bind off the last stitch.
Working the bind-off in this way prevents stitches from getting smaller when dropped off the needle, which makes the overall bind-off looser. Check out how stretchier they are in this video!
