If it were me, I think I would use a darker gray. It would make the colors POP

I like the grey,too, but do you have any way of seeing whether it's the right shade for their sofa? Greys have a lot of different undertones, like blacks and whites do, and it might really look bad if they don't work well together.

I with many of the others - Gray it is!

I like the gray best but if it clashes with the sofa gray it may not be the best choice.

I would use white.

IMHO white or black.
The white will give a fresh crisp loo. The black more dramatic.

While grey would be nice ... unless you can match to the grey couch, you are running a huge risk that they will not, and thus, your quilt will look disastrous with the couch.

I agree!

Gray for me, too. Gray is the new white in the quilting world.

The grey has a more elegant look where the white looks so plain.

Ask your niece which one SHE prefers. I always check out the colors with the person getting the quilt. Then the color isn't my problem/fault any longer.

Gray makes the other colors stand out. So I vote: Gray.
