I stumbled across this on another blog (Journey to my Father's House) and discovered that there's a way to make your own book, right from your computer. It would be cost-prohibitive if you were making several books (to sell, for instance), but if you only wanted one for a keepsake, I'd call it reasonable. I'm thinking of putting together a selection of some of my favorite journal and blog entries in book form, just for myself.
As I understand it, you download the software, put your book together, and then order it; you can get hardback or softback.
Books like this would make good Christmas gifts for family, too.
