I created this chart as part of my series of free crochet patterns for mix and match afghan squares. Along the way, I've been finding lots of other interesting uses for the squares in the series. I've made all of them into afghan squares, and I've also turned a couple of them into crocheted potholders and other things.
So with that in mind, I encourage you to use this chart any which way your imagination prompts you to.
Here's how I used this chart:
To Crochet the Afghan Square:
Each grid on the chart represents one single crochet stitch. There are two colors on the chart, but the finished afghan squares each have a third color, which is added afterwards in surface crochet slip stitches. Check out some photos of the finished afghan squares here.
You can use any colors you like to crochet this design. If you'd like to use the same colors I used in my sample square, you'll want to use Caron's Simply Soft "Bone" as the main color, and "Blue Mint" as the second color.
For the color changes, I used the tapestry crochet technique; this means, basically that I crocheted overtop of the unused color, sandwiching it inside each stitch I crocheted with the active color.
To begin working this chart, you'd crochet a foundation chain of 26 stitches, and then single crochet in the second chain from your hook. Then you'd begin working the charted design. If you look at the chart above, you'll see that the first five rows are solid single crochet stitch worked in the main color (Bone.) When I made my sample square, I crocheted overtop of the second color starting from the very first row. I recommend doing this in order to keep a consistent gauge (and consistent tension) throughout the square. If you do not crochet overtop of your inactive color, your first five rows could potentially end up being a bit shorter than your colorwork rows, because the inactive yarn can add a bit of height to the work when you are crocheting overtop of it. At least, that has been my experience.
The afghan squares in this series all have simple slip stitch edgings. To work the edging, just crochet two rounds of slip stitch around the outer edge of the afghan square. You can use any colors you like for this step; for my sample squares, I used the main color, Bone, to do this.
Beyond the Afghan Square:
There are other ways you could use this chart; feel free to use it for filet crochet, cross stitch on crochet, and possibly for other crochet techniques. You could also use it for traditional cross stitch or other needlework techniques. If you do use it for any of the above techniques, you may wish to dress it up with surface crochet or embroidery, to make the checkerboard chart stand out from the background.
