Here is an awesome book on Button Crafts.

Button Girl
by Mikyla Bruder "More than 20 cute-as-a-button projects."
If you're a weekend crafter, into buttons, or just looking for something fun to do with children, you should take a look at this book. The projects are relatively simple to create, with great results. It contains projects such as: Hip Ribbon and Button Belt; Snuggly Scarf with Button Trim; Slumber Party Slippers; Button Rings; Button Earrings; Button Napkin Rings; and Button Coasters.
Below are photos of a button necklace and hair clips I made.

This book contains lots of big photographs showing the finished projects.
Sidebars list all the items needed like a recipe. The spine of the book is a spiral wire which allows the book to lay flat while you work. Very convenient for reading directions while making the projects.
I found this book at JoAnn's Fabrics for $12.95.
