Each side of the arch is actually 2 pieces held together with the Christmas lights/wire. To stabilize the pieces, there are metal prongs from the top piece that into holes on the bottom piece. Our left leg was on the right side and the right leg was on the left side. The only way to make it work would be to cut the wires - ruining the lights - and switch the legs. Also, there is a stand that connects each arch to Mary and Joseph on each side. The arm that hooks onto the figures were both facing the same way. Thus, it would only connect to and hold one of the figures. It was soldered in place, so we could not remove it and turn it the correct way.
