Prepare needle and thread and iron clips. The four sides are neat, fix the left side of the picture (data) with clips, and set 3 or 4 points according to the length of the book. (At least 3 points, marked with a pencil. ) It's best to borrow a small electric drill, (hand drill can also be used, usually with a 2mm drill) aim at the mark drill, and then tie it firmly with thread, and it's best to smear the binding line (back of the book) with glue. (You can't use perfume, it will grow worms after a long time. ) Finally, paste the cut cover paper.

If you want hardcover, first print the title of your own design on the cover, so that the bound book is hardcover.
