    Materials Needed for Joining with Slip Stitch

    You'll need two elements to join. This demonstration is with afghan squares, but you could use this technique to join other things such as the seams on garments.

    Crochet Hook: It's best to use the same crochet hook you used to crochet your squares or pieces.

    Yarn: For best results, use yarn (or crochet thread) that is the same fiber and same general weight as your squares.

    To crochet the join, you'll use a yarn color that matches your squares. The demonstration uses a contrasting color so the work is visible. But for joining these squares permanently, you would choose a color used in the outermost rounds of the squares.

    Since the slip stitch join is asymmetrical, work from the wrong side. Technically, it would be possible to join the squares from the right side of the work, but the asymmetry won't be noticeable from the wrong side, whereas it would be on the front.

    Hold your squares together with the wrong sides facing outward and the right sides facing each other. Decide which loops you want to work through. You'll get different results, depending on which loops you choose.

    For this tutorial, you are working through the outer loops, meaning that when you hold the work facing you, you are working through the front loop of the square closest to you, and the back loop of the square farthest from you. If you'd prefer to work through the inner loops, you could do that instead. Either method will give you a reasonably sleek join. Do not work through all four loops unless you want a hefty (and uncomfortable) join with an obvious ridge on the wrong side where the pieces are joined.

    Insert your crochet hook into your chosen loops, as pictured. Unwind a bit of yarn and prepare to pull up a loop; you'll want to leave at least six inches of yarn at the end to be woven in after you are finished joining your squares.
