I had bought a tree skirt version of that pattern - or at least it looks like that pattern. I have yet to make it. It is on my to do list though - one of these days.
It was called the Golden Ratio tree skirt. I didn't see it on the quiltcampus website although the spidron is. That's also on my to do list.
Yours is gorgeous!!
Thanks for the reminder lol. My quilt cup runneth over lol
