Since I have nothing better to do while I rebuild my NAS backup system, I am wondering what kind of plywood would be best. I want it to be nice-looking, but not terribly expensive. I'll coat with a matte poly over the design.
A guy at work from Wisconsin has made a couple. He integrated cupholders that flip out from the back legs, so when you are throwing you can set your drink down. Of course when you aren't throwing you're drinking, so there is no risk of spilled beer. I think the cupholders were built into the legs so you could fold the cupholders up, then fold both the cupholders and legs into the back of the cornhole box for storage/transport.
