Start with a magic circle or a foundation chain of 3 joined with a slip stitch to make a ring.
Ch1, 7dc into the ring, join with a ss into ch1.
Starting in any stitch, ch2, 5dtr into each of the next 3 stitches, 1htr in the next stitch, 5tr into each of the next 3 stitches, 1htr in the next stitch, join with a ss into ch2.
Fasten off and weave in the ends.
Dtr - simialr to a tr but wrap the yarn around the hook twice before entering your stitch. When you draw back through your stitch you will have 4 loops on your hook and you take these off two at a time.
