As the flattest and the smallest of the crochet stitches, the slip stitch is one of a crocheter's essential skills, because it's just so useful! If you’re crocheting in the round, the slip stitch is the finishing stitch to complete that round. The slip stitch is also the master of joining two pieces of crochet together (very handy when it comes to making hats), and is the (not so) secret weapon to fastening off your yarn so your craft is always neat and tidy. This utility stitch is a foundational technique that will serve you well as you take on new and exciting patterns.
