Beautiful blocks, but if you don't sash it will appear as 1 large piece of fabric and the blocks will be lost.

Green that is in the fabric would look great!

Have you considered using a rose color baetween them. That would be my vote.

I agree. I'd go with green or gold sashing to set off the blocks. Your blocks are beautiful.

Sashing yes!
Both green and gold would definitely work... however, the look that each would give would be different... gold = elegance, green = bright.
Either way it will be beautiful!!!

I think I would audition some different colors that are in the fans and see what looks best to you

It calls "pink" in my head. Hard to say on the green because the other tones in the fans don't show up well in the pic.

have you tried lilac? from the photos every fan seems to have a touch of lilac. Try it out and see

I think gold in between would set off the blocks perfectly.

You will probably think I am crazy, but I think black sashing might be good. The blocks are so beautiful and I wonder if a colored sashing might take away from the block centers. Just sewing the blocks together w/o sashing might look too plain. Again, sort of crazy. Come to think of it, I did a quilt with a black background that had your colors in the block centers and I used black sashing. I really liked it.
