This chart accompanies a free crochet pattern for a gingham check baby blanket. There's another coordinating chart in white and green that is also part of the baby blanket design. You are welcome to adapt this chart for other uses if you like; there are many ways to use it in other crochet and needlework projects. The instructions given below will help if you plan to make the gingham check baby afghan.
Skill Level: Intermediate
Yarn: You'll need two contrasting colors of yarn. If you want your squares to turn out the same size as mine did, I recommend using yarn that is a size 3 on the Craft Yarn Council's standard weight system. To crochet my sample square, I used Bernat Softee baby yarn in pale blue and white.
Crochet Hook: I used a size H crochet hook to crochet my sample squares. This might or might not be the hook size you'll need; you can use it as a starting point and then adjust as necessary to achieve the correct gauge.
Other: tapestry needle for weaving in ends
Gauge and Finished Size Information:
1 square = 10.5" square.
If your squares do not turn out totally square, that's OK, but it means that your blanket will not be exactly the same size stated in the pattern.
I recommend that you measure your first square carefully and then do a quick bit of math to make sure you'll end up with a blanket that meets your needs. Just multiply your square's width by the number of squares needed across (receiving blanket size = 3; crib size = 3; twin size = 6.) Then multiply your square's height by the number of squares needed down (receiving blanket size = 3; crib size = 5; twin size = 8). Those will be the approximate dimensions of the blanket before the edging is added; the edging will add a bit more onto the actual finished size of the blanket.
If your square turned out way too large or way too small, you'll probably want to try again with a different crochet hook.
Abbreviations Used in This Pattern:
Using blue yarn, ch 46. Sc in 2nd ch from hook.
Follow the chart above to crochet the checkerboard pattern using the tapestry crochet technique. You'll want to carry your inactive yarn color so that you are crocheting over top of it as you go. I recommend carrying your white yarn from the very beginning. Then you can just pick it up when you need it. If you are not familiar with this technique, you may wish to take a look at my tapestry crochet tutorial to see pictures and step-by-step instructions for how to do it.
When you are finished working the chart, end off and weave in your ends.
