I like it without the sashings. It is lovely with just the blocks. Maybe a border using one of the colors in the blocks.
Here is a pic of my crumb blocks with just a border around them. It's 42 blocks..6 across and 7 down. I didn't think it would look right without sashings but I like it with just a border.
Maybe you could audition some solid color fabrics as borders with your blocks just to see how you like it. Perhaps it won't work but it's worth a try.
Good luck and let us know how it works out.
Have a great day.
