Black is what I would use.

I agree, black for me too.

Black. It is such a terrific way to may colors and print POP!!

I like the black, it makes your colors "pop".

I like the black best because of the maximum contrast factor. However, the white is nice, but, the impact is less dramatic. I don't think you can go wrong with either choice. Don't forget to show us what you choose.

I think either the gray (grunge would be my pick) or black would work and just depends on the overall look you want. The gray will be soft, the black dramatic. Personally, I would not use the white as it just seems a little flat to me.

I like the grays but darker, maybe more of a charcoal than the ones you have shown. See the gray background in the leafy fabric? I shy away from black as it tends to fade with time and becomes kind of an ugly brown. If it has polyester in it, that seems to hold the color better though. You have some beautiful fabric there!

Thanks for showing us the grey. I think Illinois is on the right track. I would take the fabrics to a store and try them against an even darker grey. But if you only want to shop your stash, I think the grunge grey or the black would be okay. I would definitely not use the white.

I like the black but you could try a dark charcoal grey too.

Love the black with those pretty fabrics!
