I want to build some bookshelves. What's a good material to use for the shelves themselves - around 30 cms deep?
I know this sounds like a daft question, but I want it to be reasonably cost-effective as the finished shelves will be 2.7m high by 3.2m long. At say 11 shelves x 3.2m, that's an awful lot of material (35 linear metres) to purchase just for the shelves, without any uprights.
I'm thinking of just painting them gloss white, although I might compromise with a laminate finish.
We've got lots and lots of books lying around the house to load onto it, so it needs to be pretty strong. I was thinking that MDF isn't that strong or would need a lot of support to avoid sagging.
Any ideas?
