So I have the big rectangle of wood, but not the legs. What can i use to improvise?
Play on your stomach. Find something else to stand the table on. Have it on the floor and play on it anyway.
Stacks of books, cinder blocks, milk crates, two chairs, friends on their hands and knees…
Set it over the bed of a pickup truck and go mobile ;)
Put it on one or two smaller tables.
Saw horses!
