Slip stitch is the shortest of all crochet stitches. Unlike other stitches, slip stitches are not often used on their own to produce a large piece fabric. The slip stitch is used for joining, shaping and, where necessary, to move the yarn to another part of the fabric for the next stage. Step 1 Insert the hook into the work as directed in the pattern. Yarn over and the pull yarn through the work and the loop on the hook in one movement. Step 2 When working into previous rows, yarn over and pull the yarn through both the work and the loop on the hook in one movement. Step 3 To join a chain ring with a slip stitch, insert the hook into the first chain, yarn over and pull the yarn through the work and the loop on the hook. Slip stitches may be used to make stretchy crocheted ribbing. To make ribbing, start by chaining for the width of the item, not the length. For example, if you are making a hat brim, you would crochet just a few stitches for the width of the brim, not the number of stitches needed to go all the way around your head. Next, slip stitch into the back loop only of each chain across the row. Chain one and turn at the end of therow. Again, work into the back loop only of each stitch across the row, then chain one and turn. Repeat this row as many times as you would like to make the fabric the size you want.
