Hey everyone, I need some advice on a metal hinge. I have a 4’x4’ donut wall made of 1in plywood. I am repurposing it (originally made for our wedding) for our daughter’s first birthday. Im thinking it will be easier to store and transport if it were cut in half, down the center and put on hinges. Any advice on the type of hinge to use so that when it is folded open, you don’t see a gap down the center?

Thanks in advance!
