Quilting on a quilt along

I am quilting along with Oh, Franson to make her very cool mod sampler. I wanted to make a rainbow quilt, but wound up working with my fabric stash to make a red and orange quilt. I have finally finished all the blocks and was ready to sash, when my mother decided to interject. Apparently my sense of style is quite questionable and the fabric I chose for the sashing is not right. Okay, so after that wonderfully affirming discussion I have agreed to wait until I find something that works a little better or am sufficiently far from home that she can't throw a fit.
