This is what I think also. You have many other color choices if you choose to use sashing to really make your blocks POP. What size are your blocks? Are they enough alone to make the quilt the size you want? Or would you need to make more blocks for your finished size? Just a few things to consider.
Your blocks are really nice :-D
