To prepare your squares for joining, it is a good idea to work an even row of single crochet stitches around each square. For the Whovian CAL, we will be working 3 sc sts per block.
Below is a sample chart for a piece worked in the C2C method. This block consists of 5 rows. I have marked where the square starts (black star) and where it ends (white star), as well as where you would turn at the start of each new row.
Using this sample square, I have diagrammed how I would work the single crochet border.
- Starting where the C2C work ended (at the white star), you would pick up your border color and chain 1. Then work 1 sc in each of the 3 sl sts of the first block.
- For the next block, work 3 sc in the gap created by the chain sts.
- If you come across a slip stitch that was created when decreasing in the C2C method, skip this stitch. In the diagram above, the next space following our last step is one of these slip stitches. Skip the slip stitch. (It’s important to note that when you’re single crocheting around a larger piece of work–say a 30×30 piece instead of a 5×5 piece–you will have more of these slip stitches to skip.)
- Work 1 sc in each of the 3 sl sts of the next block.
- For the next block, work 3 sc in the gap between the second and third double crochet stitches of that block. (See diagram)
You can see how this pattern gets repeated. You single crochet in the slip stitches (or the chain stitches, whichever applies), skip the first slip stitch on the decreasing rows, then single crochet in the gap (whether the gap is created by turning chain stitches or by double crochet stitches).
Note: I do not work any extra stitches into the corners of the square. I haven’t had any problems with the finished corners laying flat, so I didn’t think it was necessary. If your stitches tend to be pretty tight, however, you may want to try working 2 single crochet stitches into each corner.
Using the method above, and doing the math, the final border should be 3 single crochet stitches per exposed side of the blocks. There are 120 exposed sides of the blocks (30 per side of the square), so you should have 360 single crochet stitches around the square as your border (unless you work 2 into each corner, which should leave you with 368 stitches).
Here is a video showing how I’m working my border around the squares. If you have questions, please let me know! I’ll do my best to answer them.
To further prepare your squares for the way I will be joining, use white yarn and work 1 single crochet in each stitch around, creating a secondary border. When we join with white yarn, the secondary border in the same color as our joining color will make the whole process look cleaner.
Why make a border in the background color if you’re going to do one in white anyway?
If you were to work your first border in white on a square whose background color isn’t white, then the sttiches of your white border could look quite messy. By working a secondary border in white around your first border, you guarentee that your stitches are even and level with each other, making it look nice and clean.
