Large wall hanging - thoughts on backing fab
I am making a tie wall-hanging and it is going to be aprox 60" when done. I haven't made this large a wall hanging before with this much weight in the center. Do you think it needs a heavier backing or is a cotton quilting fabric OK? With quilting it may be OK but just wondered what others thoughts are. I don't want it to sag in the middle. I am attaching a picture of tentative layout. I am thinking a border or two and maybe a strip between center and triangles but haven't decided on those layout options yet.
What do you think heavier backing?
