This pattern has been updated to show more details on how to make the Catherine Wheel Stitch.
You can do any color variation you like for the wheels. I used three colors for the alternating wheels of this blanket.
To begin, chain a multiple of 8 plus 4 using a 5mm crochet hook. Then put 3 double crochets in the fourth chain from the hook. Skip three chains, and then single crochet in the next chain.
Now skip three chains again and put 7 double crochets in the next chain. Repeat from * across.
Because this is how the beginning row is done, if you're doing alternating colors then you'll want to change colors at this point. To change colors at the end of a row, leave the last double crochet uncompleted.
Then add the new color with the old color and pull a loop through the last two loops of the double crochet.
For row 2, start with a chain 3. To make the bottom half of the wheels, you'll need to do double crochet 7 together.
Yarn over, insert hook into next double crochet. Yarn over and pull up a loop then draw through two loops on the hook. Don't complete the double crochet!
Just repeat the process you just did using the very next double crochet, and again, don't complete the double crochet.
Do this process a total of 7 times.
I used an ink pen to show you where the two loops of each double crochet that I pulled through; the loops on the hook are the endings of the double crochets without completion.
Now, you'll want to yarn over and pull a loop through all 8 loops on your hook.
Next, chain three and single crochet in the next double crochet.
Repeat the dc7tog across for the row.
When you reach the end of the row, put a single crochet in the turning chain. Row 3 completes each of the wheels. Chain one then put one single crochet in the first immediate single crochet. Now just put 7 double crochet in the ring of the cluster from below. Then single crochet in the next single crochet and the wheel is complete.
Repeat the process across to complete the row.

Row 4: Join next color with slip st in 1st sc, ch 3, work 3 dc tog in next 3 dc, ch 3, sc in next dc, ch 3, *work 7 dc tog in next 7 sts, ch 3, sc in next dc, ch 3. Repeat from * to remaining 4 sts. Work 4 dc tog in these sts
Row 5: ch 3, 3 dc in 1st st, sc in next sc, *work 7 dc in center of 7dctog set, sc in next sc. Repeat from * across to remaining 2 sts. 4 dc in last dc.
Repeat rows 2 through 5 to desired length.
For the borders, I added one row of sc all the way around followed by a row of dc all the way around.
