When I do smaller QFK I make them pillow case style. I'm with you Bringing binding from the back is a pain. If you are self binding with back fabric leave no more the 1 1/2" of backing to turn over.
I spray glue batting to backing then sew around 3 sides, turn then finish the end, the last couple i made I turned the backing to the front for an added color. That was easier then turning 3 layers the stitching edge. I also think this will wear better.
My local coordinator suggested doing pillowcase style.
