A single crochet border adds a finished look to a piece of knitting, and is pretty easy to do even if (like me) you can't really crochet. For the purposes of this tutorial, a contrasting color border is being added to a swatch of Stockinette Stitch, which will not completely remove the curl but still gives a nice look to the edge.
To begin, you'll need a crochet hook and some yarn that's the same weight as your project.
Pick a corner and start on the right hand side of the work, putting your crochet hook into the first stitch, from front to back. Then put the yarn over the hook (in crochet, this is sometimes called "yarn over").
