The crocodile stitch is a crochet technique that creates a layered effect on knit scarves, bags or sweaters. To accomplish this distinctive textured stitch, knit multiple crochet post stitches around a row of double crochet stitches with alternating spaces to create a crocodile scale pattern.
The crocodile stitch is an advanced crocheting technique, largely because it requires knitters to create post stitches that are exact mirror images of one another. This means that half of all stitches in the project have to be sewn backwards. There are several video and picture tutorials on crocheting websites and blogs, such as AllFreeCrochet.com and MyMerryMessyLife.com, that offer step-by-step instruction on the crocodile stitch.
