by time that 3/4 melamine starts sagging. hell have moved on to a different hobby haha. the melamine it self is really strong, alot stronger than the wood it self so i dont think hell have any worries. another thing they do make melamine strips that you can glue on to the sides of each sheet to make it where it looks like it was never cut.
