I recently moved to a new city with no furniture, naively assuming that I'd be able to afford a couch right away. I'd always thought couches ran somewhere in the market of $200-$300, but much to the dismay of my heart, butt, and wallet, they're more like $600-$700 - and that's merely for something half-decent. I wish I had seen this awesome tutorial before committing myself to an expensive couch - the end result is actually nicer than most of the sofas on the market!

The builder took weeks to meticulously plan the construction and design of this sofa, because he claimed he had never worked on a project so big. His only two goals were that the sofa be large enough to sleep on, and be modular so he could move it around.
