This tutorial teaches you step-by-step how to decrease in single crochet.

    Understanding What It Means to sc2tog

    Before we get into the steps of decreasing in crochet, it's important to get a fundamental understanding of what you are doing. You are going to complete the first part of a single crochet stitch, move to the next stitch in the row and complete the first part of the second single crochet stitch, then finish the two stitches together. This is one it is called "single crochet two together". The effect is that you create two single crochet bases with only one top, decreasing the number...MORE of single crochet stitches in the row in which you are working. Decreasing is used for shaping, such as when you decrease little by little to get a crochet triangle.

    You are still making the first single crochet of your set of two so you will continue proceeding like normal by doing a yarn over and pulling up a loop.

    However, this is where things change from a sc to a sc2tog. You are not going to finish the first single crochet at this time. You are going to move on to making the next single crochet instead.

    Without finishing your first single crochet, begin your next single crochet as if you were working normally. This means that you go ahead and insert your hook into the next stitch. For now, just ignore the two loops already on your hook from the previous single crochet.
