Asian fans

A couple weeks ago, I bought some fabric to use to (hopefully) complete the blocks for my Asian fan quilt.  Isn't this rich!?!
Now I have to try to make templates for the two pieces.  Am nervous.  I'm using a pattern, but I've modified it enough that I'll have to wing it.  Worried I'll mess it up & waste fabric. :(
I'll be brave. Just not today.
