Wow! I guess I have my work cut out for me! I kind of like the idea of a muslin in the middle with the flannel backing or using 2 layers of flannel. If I used corduroy for backing, I don't think I'd get the chenille effect on the front that I'm looking for. Besides, isn't corduroy an apparel fabric? I just don't see corduroy as an option. I definitely am glad I asked about this, as I would never have thought about the stretch stitches and doubling them too! This quilt will last my grandson forever and a day! Any more thoughts on the corduroy?
