I bought the template thinking it was a Dresden by another name. I found it needs 10 pieces to make a 1/4 circle fan. My pieces were 7" tall and the fan is 16.5" tall. The center will need to have a radius of 9.5".
For my purposes its not good but some of you more advanced quilters might make a medallion for the center (18") and then you could surround it with the circle.
(I tried to attach a picture but can't figure it out)
