Question... I've been looking at Looping GM bags for a while now, and I've noticed something that is worthy of a question...at least for me. I've noticed on some bags, there is one, unbroken piece of monogram canvas that wraps around and makes the bottom of the bag. And I've also seen bags that have a seem in the very center of the bag, as two pieces of mono canvas were used. What/why is there a difference? Thanks!
