If you're fortunate enough to have the space, getting a nice desk to work on can be expensive. This man built his wife an incredible desk that suits all her needs. It only cost him $112!
He took 3 IKEA bookshelves and some supplies from the hardware store. He then arranged the bookshelves into the shape of a desk, then connected them. The 3rd bookshelf was added as an "L" shape. Check it out.
