You will need the template files, which include instructions and all you need to print out a chess board and all 32 pieces (another advantage of this chess set: if you lose a piece you can just print it again). All you need to supply is a black and white printer, letter-sized paper, a pair of scissors and a bit of patience -- though I should clarify that I designed all the pieces to be easy and quick to make, so you won't need superhuman patience, just a little.
I designed the template, a 10 page PDF document, which I usually sell on my website
for $3.95 -- but I've been on Instructables for a while, and I consider this is a site for sharing, not selling. So until July 31st 2013 or until 500 people download it I'm offering the files for free. When you "buy" it enter the code INSTRUCTABLES and you 'll pay me $0. If 500 people beat you to it, then use the code 2LATE and you'll still get 50% off. Click here to get the PDF template UPDATE
: The 500 download limit has been reached, but the 50% discount code 2LATE will still work.
