The first step is to print 4 full sheets of paper, folded in half to make 8 physical sheets of paper, or 16 possible printed pages. In the video, the lady only prints on half the pages, and puts page numbers on the others. She then draws evenly spaced holes on the binding of each signature, and sews each of the signatures together. You then start sewing signatures to each other starting from the front of the book to the back of the book. You sew the binding of each adjacent signature with a piece of string twice the length of the height of the book. You then continue sewing each cluster of signatures together until your book is complete. You then put some binding tape, the front and back cover of the book, and your masterpiece is complete.
