i like the black

How about putting a black thin border around each block against the white background. Just using a black or white background could kind of depend upon who the quilt is being made for.

Of your two photos I prefer the black, but a steel grey would be better yet. The grey would pull some lovely colors out of your blocks and pull the whole quilt together.

Definitely the black. It makes the colors pop!

i like them both. it just matters if you want the colors to pop or be more muted. pop go for the black more muted go white.

I like black too.....but to me the white made it look brighter 😳

My Husband also agreed plus he said that it reminded him of the Pink Floyd album cover about a zillion years ago. Enjoy and Happy New Years.

Black is the one i pick

Black and you wonderful blocks will 'pop'.

Both give a totally different look. The white gives it a softer look and the black makes it all very bright. You need to decide where you are using it and what pleases your own eyes.
