I really, really like the orange-red color!

The pale blue washes out the other fabric not a good choice the mauve - purple - red are the best choices makes the quilt that you have worked so hard on really pop
Hey you wanted opinions you will do the right thing on your own seems like you have it all together pssssst Which do you like???

The redish/orange in my eye brings it to life

Either of the top two would be fine, but not the blue. That's my preference. Like the backing fabric.

i like the orange one

Gotta go with the orange-red. what are the colors of the room that it will go into. beautiful fabric - would like some of that. good luck with your choice .

Orange/Red.

While it is not a color I normally like, for this I really like the orange....

What color is the binding going to be? That might make a difference.

What does the front of the quilt look like? I like the purple
