I actually got the idea from Shanty 2 Chic and I thought I would share my take on it here. It was super simply...I just kreg jig'd the boards together and built a frame to the size I wanted. I bought the aluminum from Lowe's and cut it down. I actually built 6 of these so I could give 5 away as thank you gifts. The price for all 6 was under $50 and I think only about $30 of that was the materials to make the boards. The rest was spend on the stuff I made for the boards.
