White

I say go with no sashing and let the secondary pattern show.

love the block, red or white

I like the red...or no sashing at all. Have you thought about the floral print for sashing? I just finished that block. My sewing neighbors are doing all of the Paper Pieced "State Stars". We are doing one a week and going in alpa order just like the book. Yours looks great.

ohhhhh .... beautiful! My preference....definitely the red.

Good luck!

Red

Red! For sure not the black. Nice blocks.
