Continue in this way, around the circle, making 1 Popcorn stitch in each chain space, with 3 chains between each Popcorn stitch. After you finish the last Popcorn stitch, make chain 3. End round with slip stitch in the top stitch of the first Popcorn stitch (picture 13)
Now we're going to make a Cluster stitch. Insert a new color in any chain 3 space (between 2 Popcorn stitches), and chain 3 (picture 14)
