Make your own business card holder from an old book! This looks great, is practical and will take you no more than 15 minutes.
All you need is a book. First you remove the binding cover by hand, you should be able to tear it off gently. Then you fold every page in half toward the gutter. You now get twice the thickness on each page and the book will automatically spread out in the shape of a half-cylinder. That’s all!

I think that it would work great for reminders, notes, recipes, birthday cards, ideas, anything really!
