I dont know how large the table is, but I would get 2 smaller pieces and I would use 1/2 or better 3/4 in or more plywood. You may have to come up with some sort of center support underneath? Maybe a stack or 2 of books? You could cover one for ironing and cover the other with some self stick vinyl tiles and use it for a cutting space. On 2nd thought when I mentioned before the piano hinges, to hook them together, if the table is big and the lumber is heavy, best to not attach them, too hard to handle! That would be easier for the kids to remove as well when they want to convert back to a pool table.

The big boards I have made for my house sit on ironing boards. I got a 28x40 precut plywood board and covered with some fluffy old poly batt, stapled that down, then did the same with the topping fabric. The 2nd one I made the topping fabric with an elastic casing, so it can be removed for laundering. They do get messy after a while. If you staple the batt/ fabric down, I started with opposing corners first, then went to opposing centers, ends, etc. before filling in on the sides with more staples.

My design wall is 2 huge sheets of foam core board. I covered it with gridded flannel If I had more free wall space, I would rather have it mounted on the wall, so if you have the room, I would do that. Make it as large as you can though. Mine are not large enough when working on a big quilt.

Good luck! Please send photos when done! Would love to see it.
