Black. Good job on the blocks. Love them!

Black or white. Interview both to see which u like best.

I would go for black, it seems to enhance the other colours in the blocks. Good luck!!! Looking forward to see the finished quilt :)

Sorry yes...
Black or navy


could you add a picture with a few blocks laying on black fabric and a few with navy....
that would be helpful

I also vote for either navy or black .... any other color would compete with the blocks. Your quilt blocks are beautiful.

Black or Navy would go great.

How about a pale yellow? That might work. Maybe when you audition the sashing you'll come up with the right color automatically.

Depends on whether you are looking for a soft look in which case I would use a light color, if a dramatic look I would use a navy or dark green. Your blocks are beautiful!! I look forward to seeing what you decide to do.

Guess I'm different but think cream would be nice.

You need to audition several colors. Lay them beside it, walk away, come back and start removing the ones you don't like.
