Ditto. That block is amazing!

white if a summer quilt, red if a year 'round quilt

I think the black and red are too strong for the block. You need to notice the nice blocks first and not be overwhelmed by the sashing.There is enough contrast in the blocks for them to stand alone without sashing or I would be looking for a blu,pink and white stripe that was not darker than the blocks.

I agree.

Blue first red second

I like all but the black. Not much help. I love the block!!!!!!!

Love that block! I would use the red.

I am thinking no sashing would be more dramatic. Great flying swallows blocks.

red- yum
