I have to much blue scrappy material and not sure what to do with it. Most is from Men's shirts that I have bought around at thrift stores. Lots of checks, big and small. I just finished a Blue/Yellow so not interested in that kind of combo. Would grays and Black and alittle white work? Also considered adding a darker Red? Most of the blues a darker/softer and not the brights. any ideas?

blues, greens and blacks go with anything :D:D:D

You could do red, white, and blue, sort of patriotic. Any of those colors would be fine. Green would also work. I just try to get contrast.

Or blue and light purple. It has to be the right shade though.

there is always some use for fabric

I'd go for red or green depending on the shades of blue.....

I know this is out there but I just finished a "blue" scrappy quilt and discovered that I now consider blue to be a neutral, I was amazed everything seemed to go with it just fine.

Got any lime or spring green?
Or how about just blue and cream, to look like a very old blue and white -- all the same block.

I always think blues with browns and tans look good together. Check out Bonnie Hunter's quiltville.com website. She has some beautiful blue scrappies using tans, browns, creams and beige.
