How to Join Squares Using Single Crochet

The single crochet join is an easy and effective way to crochet squares or other pieces together. It's bulkier than many of the other joining methods; that can be either an advantage or a disadvantage, depending on your objectives. You might not want to use it on sleek fitted garments, but it makes a wonderful finish on certain types of afghans.

Unlike the slip stitch join, the single crochet join is symmetrical; this means that you could use it on the right side of the work if you want to. When used to join multiple granny squares to create an afghan, the look reminds me of a grid. This effect is the technique's major advantage.

This join is particularly nice for use on otherwise plain and simple squares; it could add quite a bit of visual interest to a design. It can add visual interest on a granny square afghan where the squares and the edging are all one color.

Here's how to do it:

    Decide on Your Joining Yarn/Thread

    Michael Solovay 

    You can use the same type of yarn you used for crocheting the pieces you'll be joining. This works best if you use the same type of fiber in the same general weight.

    You can, however, use a different color (or colors) if you like; in some cases, you may wish to use a contrasting color, and in others you might want to use a closely-matching color. This tutorial uses yarn that contrasts with the outer rounds of the squares, which are dark, but is a color that was used in the squares.

    Begin Crocheting Your Stitches

    Decide whether you want to work on the right side or wrong side of the work, and then decide which loops you want to work through. If you want the join to be on the right side of the work, like here, then hold your squares (or pieces) with the wrong sides together.

    As is true with most crochet stitches, you can achieve slightly different looks by varying which loops you work through. In this case, the most obvious choices are as follows:

    • You could work through the inner loops, meaning the back loop of the square closest to you and the front loop of the square furthest from you. This is the method demonstrated in this tutorial.
    • You could work through the outer loops, meaning the front loop of the square closest to you and the back loop of the square furthest from you.
    • You could work through all four loops, meaning the front loops and back loops on both squares. This creates an exceptionally bulky join.

    Whichever loops you decide to work through, insert your crochet hook into them and wrap your yarn around the hook as pictured at left.

    You'll have two loops on your hook if you count the slip knot you made in the beginning.

    Work a Row

    From here on out, the joining process is pretty straightforward; you're basically working a row of single crochet stitch. The only difference is that you'll work each stitch through both squares (or through both pieces if you're joining hexagons or other shapes.) Be consistent; for example, if you began by working through the inner loops, continue working through the inner loops all the way across the row.
