My Mom used to have an expression, "Don't eat the cow then choke on its tail!" If you haven't heard it before, it means "Don't get through the big/hard part and then quit/mess up at the end." You've made beautiful blocks so don't take a chance with the busy sashing. It would take less than a yard for sashing so I'd use solid for that even if you have to buy it, then decide what you want for border. Have you considered using the back side of some fabric from your stash, so it will read as a solid? Another quote, "You paid for both sides of the fabric so use whichever one works best!" (Those chevron fabrics would make pretty Dresden Plate blocks.)

Very pretty blocks. I would make a scrappy border using any leftover fabrics from the blocks.

Use them for the back... I would go with a simpler solid or tonal for the sashings. You did such a wonderful job on the blocks, they deserve to be the 'stars'.

I like the peach but I would not use a chevron fabric as I agree it takes away from the beautiful blocks you have created.

Wonderful little blocks. I agree with the others that the chevron detracts from the blocks.

Pretty array of blocks. Using a mix of the chevrons would be very busy and distracting. They would make great corner stones.

Your blocks are turning out nicely.

I like the green sashing best but whatever you pick will be good your colors are already very nice.

I'm doing this one too but fell way behind.

You have made so many beautiful blocks. Something to really feel proud of.

Beautiful little blocks! Is there any way you could use white on white or a solid grey?

Super blocks. Agree with the others about the chevron design. BrendaK
