that's beautiful. What line of fabric did you use?
Sorry, I was so awed by it, that I forgot you were asking for
quilting info. I'm sure there are others more qualified than I,
for those kind of answers. I do think whatever you do will look
good on this very pretty quilt.
I will say, since it's in columns, my inclination would be to do
something that either goes horizontal or SITD, with something
else for the smaller pinwheels. Really like this quilt a lot.
Pretty colors.
