Hope it works! Please becareful that it doesn't fall on you/or your legs! I have laminate floors, so I don't know if the carpet was the problem for you. My DH cut a piece of plywood the size of my table, used the router around the the edges & sanded it ( no splinters)! Mine was trying to sag in the middle, forget using a cutting mat on it, and my machines would dance all over it. When I used my serger, well let's just say "game on."
If yours doesn't work here's a back up plan!
Good Luck!
