This is a rehash of IAMSatisfied's chair. I did mine out of stock lumber instead of ripping stuff down.
Step 1: Materials & Tools
1x2 @ 8' - qty 2
1x3 @ 8' - qty 1
Rope (1/4" or just under) - ~100'
Using cheap wood and rope it cost about $15 from a local hardware-big-box.
Something to cut wood with (miter saw, chop saw, circular saw, hand saw, well-trained beaver)
Drill with bits (I used both a hand drill and a cheap drill press)
Router with 1/4" bit
Brad nailer (Optional)
35mm film canister (Kids, check your local museum if you don't know what this is.)
