Here is a picture of a basic fleece blanket you can get for a couple of dollars at Walmart. It is 30 x 40 inches in dimension. It has a blanket stitch running around the perimeter of the blanket. It is on this blanket stitch that we are going to attach our crochet work.
How to crochet a scalloped edging around this blanket is very simple. It is not an exact science and that is okay. Your blanket may differ slightly from the one shown above. But the overall process will be the same.
I am using an acrylic worsted weight Redheart yarn and a size G crochet hook.
First you will attach your yarn to the blanket stitch with a slip stitch and then ch 1 (chain one). You will then sc (single crochet) in each stitch of your blanket stitch all the way around the blanket. I added a few extra stitches in the corners so the blanket would lay flat. Again this is not an exact science, but a good way to do this would be make 2 sc in one blanket stitch, then only 1 sc in the next stitch (repeat this three or four times in each corner).
To create scallop: From your slip stitch you want to sk 2 st (skip two stitches--the sc in Row 1) and dc (double crochet) into the third stitch. You are going to double crochet into this same stitch a total of five times. This becomes your scallop. Then you are going to sk (skip) 2 sc (from Row 1) and sc (single crochet) into the third stitch from where you put all of your double crochet stitches.
You are going to repeat this scallop all the way around your blanket. Before you actually get all the way to the end, you may want to count your stitches and be sure that you are going to end evenly. If not, I would make a few scallops by skipping only one single crochet (in Row 1) here and there until you see that you will end evenly. No one will notice this adjustment and you will have to count your stitches (makes for very easy crocheting).
When you are all the way around, attach your last scallop with your first and finish off.
Your finished product will be a beautiful gift that was made in only a fraction of the time that a traditional afghan would have been made. Hopefully you can see that it is easy to learn how to crochet scalloped edging to just about anything ready-made. What else can you add a scalloped edge to?
