Summarize the following:
Use anywhere from 5 to 15 sheets, depending on how thick your paper is and how many pages you want your notebook to have. Try printer paper, loose leaf, cardstock, scrapbook paper, drawing paper, handmade paper, or a variety of paper types. Use a stiffer piece of cardstock for the cover, in the color of your choice.  Saddle-stitched notebooks work best when they’re left thin. Avoid overstuffing your notebook since it won’t lay flat when it’s done. If you’re using lightweight paper like printer paper, feel free to use up to 15 sheets. For thicker papers, use only 5 or 6 sheets for your notebook. To determine how many pages your notebook will have, multiply the number of sheets you’re using by 2. Each piece of paper will be folded in half, so if you start with 8 sheets of paper you’ll have a 16-page notebook. If you want to use differently-sized sheets of paper or cardstock for the cover, trim the larger sheets down to the same size as the smaller ones using a paper cutter.  If you want a rustic-looking notebook, some slight variations in size can look nice in the finished product. The soft edges of handmade paper can look especially pretty amongst other types of cut paper. If you want a neat and orderly notebook of all the same paper type, stick with a standard paper size so you don’t have to do any cutting. Place the sheets of paper in a stack on a cutting mat, then lay the cover on top. Arrange the stack so that the long sides run parallel to your body. Adjust the pages until the top, bottom, and sides are perfectly lined up beneath the cover. Place 2 binder clips on either side to hold the stack in alignment. Think of the stack of pages as if it’s a book with a spine is running down the middle. The back cover should be to your left and the front cover should be to your right.

Summary:
Gather a few sheets of paper and a cardstock cover. Cut the pages and cover down to the same size. Stack the sheets and cover together and secure them with binder clips.
