I piece my string blocks on muslin. On the only quilt I've finished I used fleece for the backing with no batting and loved how it turned out. I have several UFO string tops to finish up.
I have a great piece of flannel that will match up to one of my tops for backing, but I'm wondering if the flannel alone will be enough like the fleece was. I usually use Warm & Natural batting but that will make this quilt way too heavy.
What have you used when quilting a string quilt for backing and/or batting?
