I’ve got ~10 full sheets of .5" construction grade plywood taking up space in my garage. I’ve already built a climbing wall for the kids and a new scrap bin.
How else could I put it to use?
Jigs and more jigs. Replace any older/worn out ply in other projects (bench tops, shelving, …jigs)?
Shelves and bins for those shelves.
I’ll go a different direction than some of these other comments because it’s a project I’m planning on building soon. If you have cats build some homemade cat towers. You can cover with carpet/fabric to make them easier for cats to climb and hide the imperfections.
I don’t have cats but that would be a great use for it.
Shed. Then a second Shed.
Look at Arthur ‘Two Sheds’ Jackson over here.
To be fair, 10 sheets of ply is going to make two very small sheds.
