Actually I used only one layer of flannel between the top and back,both cotton and it was really easy to quilt,I didn't baste it I did use a very little basting spray on the corners,but it was the easiest I have ever put a "sandwhich" together,I didn't even tape down the bottom to the table,did everything not the way to do it and both of the quilts I did like that are beautiful on the back,where I always had trouble,bunching up.But I live in the desert southwest and although it does get very cold in the winter(for us anyway) it still keeps very warm.
