I used MDF wood, since it is stronger than plywood. It is heavier, though. I glued indoor/outdoor carpet to it using spray on glue, and put velocro on the bottom of all my pedals, and they stick really well. I screwed on 2 drawer handles so it's easy to lift, and screwed on some rubber furniture feet on the bottom to stop it from moving on wooden stages. It fits perfectly into a bass guitar case which I bought used at a pawn shop for cheap! (I had to modify the case a bit, mainly I removed the storage compartment in the middle)
