I've made the Big Star Quilt exactly like Jenny's tutorial - same fabric etc.

The Big Star Quilt - Quilting Made Easy! - YouTube

There's not a lot of choice of 108" wide backing fabric here in the UK (I don't want to piece) and I have two samples. One is a small patterned dark brown which blends well with the quilt top colours - the other is a cream on cream design. Which would you go for - cream doesn't seem right for a backing somehow.
