I require a bookshelf as evidenced by the piles of bound paper on my floor. I was going to get something from ikea but my love of floor to ceiling bookshelves is strong. I still may go to Ikea, but I am also going to price up a home made version.
The design of the billy bookcase is not that hard to imagine, Whilst doing the design I also thought about how I would actually put it together. They normally use dowel bits and some screws. Again pretty easy. However, I have discovered it might be difficult to drill the holes in the shelves whilst also keeping it straight. I could use angle thingys but that would be crap. Going to check out bunnings tomorrow for actual wood prices.
