I do mine like that. 7-8 solid pinwheel3.jpg
Just do the hair-hardware.com
pinwheel using the template. Change 2 things, don't overlap your loops, butt the edges of the ribbon up to one another. Also, position the tails directly over the loop before you stitch.
You can see mine are only semi-overlapped. I didn't put my tails exactly on top of the loops; only halfway. That is how I like mine.
