I agree, no stabilizer. She may also want to go with no batting, or just a layer of pre shrunk flannel. Cotton terry doesn't stretch, and since it's a memory quilt, they have been laundered enough to not worry about shrinkage. The only thing that might cause a piecing problem is if they have that decorative woven strip with no loops as this sometimes shrinks more than the rest of the towel. Just something she may have to work around.
