One of the most common questions I’m asked is, “How do I make my edges look nicer?” Many knitters have heard that they should slip the first or last stitch of each row, or that they should pull the first stitch tight, but none of those methods really does the job. I have a better way and it’s really easy!
Knit or purl the first stitch of the row as usual, without worrying about tension. Stick the needle into the next stitch, but before you wrap it, give the working yarn a hard sharp tug, then go ahead and wrap and complete the stitch as normal.
This is a variation on tightening the first stitch, but it works much better than just tugging that first stitch tight. When you just tighten the first stitch, it will just loosen up again as you move the needle to stick it into the second stitch. With the needle already in the second stitch, the first one will stay nice and tight.
