What's the best way to mount floating 32"X15" bookshelves that are made of 1" thick pine boards? ?

We were going to use a single piece of 1"X1" pine to mount to the studs and then the bookshelf to the piece, but can't find such a piece of pine locally. We're looking for something we can do ourselves (as amateurs), but that will be able to hold a fair amount of weight.
