it isn't a false backing. it's an extra backing.
where is it written that the front and back of a quilt must be quilted in exactly the same way? i have used this method more than once in more than one way. you end up with a very interesting quilt all the way around. (pun fully intended. :lol: )
you're a big girl and should do as you please. i just don't see a purpose in tearing yourself up over something the child who gets your quilt wouldn't care about even if she/he knew we did.
