I have a softcover book. How can I make it hard cover. Thx?
Answers:
You can't really change a soft cover book into a hard cover book; there are simply too many differences between the binding methods.
What you CAN do depends somewhat on the quality of the binding of the soft cover book and what you want to accomplish.
Probably the simplest thing you can do is to apply a layer of clear plastic adhesive-backed lamination to the book cover. This will offer quite a bit of protection to the cover although it won't do anything to help the binding of the book itself.
You can find several ideas and kits for covering your books at How do you know if you're being followed by the law?
