Each color band two rows
Second row of red not increased (total 47 stitches)and used hdc rather than sc, little more height.
Top row, popcorn stitch 23popcorns.
Slip stitched red border followed by purple slip stitch row. Used 3 sc on the points. Could have used 5 sc to lay flat. I did not feel like making half rainbows. Unique shape is okay.

Made 29 motifs. Needed to buy 3rd skein of white. Plenty of yarn left over.
I did not like sewing it together.
About 14”x7” (centerline)
