Well seeing as my Spanish teacher is making her students put a book cover over our Spanish textbooks, I decided to save money and make my own! This way I can just draw whatever I want on it :)
Get a paper bag. Mine's from Albertsons :)
Rip the bottom open and cut a line from the bottom to the top so you have a long roll.
Grab your textbook and place it on your paper bag. Fold the paper to the top and bottom slightly so you can see what the height of the book is.
Fold the creases down and make sure it's the same height as your book. You wouldn't want it to be too small or too big!
Fold the paper around your book and leave about 2.5 inches hanging off each side.
Cut out the extra paper.
Tape the corners of the sides. (As shown in the picture) You can see there is a slight opening in your paper bag. Place your book cover in this opening.
Do the same for both sides and tape the inside and outside cover so it can stay.
And tadaaa! You have a book cover that you can keep as it is or even draw whatever you want on it!
