The cover can be covered in paper (including paper that’s been printed on) or cloth. If you have special material you’d like to use, you can even make your own book cloth.
I recommend this tutorial to learn how to make a basic Japanese Stab Binding.
Japanese stab bindings aren’t as complicated as they look (once you’ve got the hang of them). After you’ve tried the basic stitch, try the Tortoise Stitch (shown in the image above). Note: this tutorial does not have sound, so will be harder to follow if you haven’t ever tried a basic stitch.
I recommend this tutorial to learn how to make a pamphlet stitch book.
This book is a modified dos à dos (which means back to back) binding. There are three books here, but can be made with as many books as you’d like. Also, when you get good at binding, I imagine you could make a dos à dos with almost any binding.
I recommend this tutorial to learn how to spiral bind your own book.
This book has a wrap around cover so you can’t see the binding when the book is closed. It creates a spine and makes the book look and feel more “finished.”
