Most people drink while working on a DIY project, in this case you'll need to drink just to get building supplies.
For your DIY glass-bottle shelving you'll need a drill, some turn-buckle eye hooks from the hardware store, wood planks for the shelves, a drill, and of course some large and stout bottles.
Drill some holes in the planks, place the necks of the bottles in the holes, use the turn-buckle to provide tension between the plans, and you're in business. If you can hit a bar and a construction site on your way to the hardware store to buy the turn-buckles you'll likely be able to put together a few shelves for next to nothing.
