This isn't a step-by-step tutorial but tire chains are simple enough to make that I think most people will get the idea.
I used jack chain from Lowe's because it is fairly easy to open the chain loops up with two pairs of pliers so you can disassemble the overall length of chain into the sections of chain you'll use. Likewise, it is also easy to crimp the loops closed when assembling the tire chains.
I made my tire chains 7 links long for the cross-chains (I have 9 cross chains per tire) and 18 links long for the two side chains. I placed the cross chains every other link on the side chains. Hopefully the pictures do a better job of explaining this.
