"Regular" paper is usually 20 lb. or 24 lb.; I am not sure what that is in gsm. So far I've found it to be too thin, actually, though I'm using an inkjet printer (modified for a continuous ink system). I've used 28 lb. and 32 lb. paper, although next time I see it I'm going to buy something thicker (36 lb. or 40 lb., assuming the pattern for commercially available thicknesses holds inductively). Thinner paper seems to be a bit too transparent, but that might be a function of the type of paper or my printer's generosity with regards to ink. Having sewn and bound a couple of books following similar tutorials, my advice is to actually get a professional print shop to make your books if you want something of professional quality[0]. Doing it by hand is a viable hobby, but even with my continuous ink system, it's probably not economical because of the time required to bind everything together. Printing with laser is probably more expensive. ----- 0. If you just want to get some notes together in a reasonably permanent form, here's my three step approach to creating usable, but necessarily "beautiful" books. First, print off your book, arrange the pages, and add a blank page before the first page and after the last page. Second, align the pages carefully, ensuring that the spine is flat. Clamp the pages together, using something flat (another book, or a piece of wood works) to distribute the pressure. Finally, apply some Gorilla Glue (or similar) to the spine of the book, ensuring that the entire spine is covered but wiping away excess insofar as that is possible. Leave overnight, or until the glue cures. The result: a surprisingly durable book from a process that takes less than 10 minutes, assuming you've got the materials handy. You can make it more presentable by adding a cover (I cut folders or cardstock into a book cover, and then glue them onto those blank pages).
