Whoa, gorgeous!! I like the definition you get with the sashing!

either way but I really like the no sashing. really cool job.

Definitely sashing. Makes the blocks pop.

I like it with the sashing but I think it needs to be a bit wider, just to give it a little more definition.

with sashing...makes the colors pop

I love the blocks! I would say this; if you have lots of time, use the sashing. If not, just leave it like it is. I like it as it is really well.
Would you share with us/me how you cut the blocks in the shapes they are in?

Both are gorgeous but I like the sashing best, I think.

Both work but I like the way the blocks blend without the sashing - so without gets my vote

Like it best with the sashing...shows it off better!

Beautiful! I like the definition of the sashing.
