Collapsible Cornhole Boards

I had the idea to make a collapsible set about 4 years ago while living in the dorms where space is at a premium.  This is my second (lighter, thinner, just as sturdy) set, as the first was destroyed by rain and drunkenness last summer (I had mistakenly lent them to a less than responsible friend for a weekend).  They collapse to just over 2" thick when stacked.  Everything was hand painted by my girlfriend and I.  The boards are 1/2" MDF and the braces are 1/2" Birch Plywood.  I also used 36" continuous (piano) hinges. Weighing in at 18 pounds each, they also can support my 187 pound body.
