This is a book cover made from a Victoria's Secret bag. It was made for a large book so it was very convenient to carry around. Also, people without one will want to know how they can make one.
Step 1: Cut Bag to Fit Your Book
I added a little bit more space on the sides to make room for the handles.
Step 2: Make the Cover for Your Book and Make Sure the Handles Face Outward... Need I Say More?
