I learned how to make this really cute bookmark 
here via Pinterest, but I decided to make my own tutorial. :) Enjoy!
Supplies Needed: Felt, Scissors, Chalk (or any writing utensil), Needle and Thread. 
|  | 
| 1. Fold your felt to make a triangle. | 
|  | 
| 2. Using your chalk/writing utensil, draw half a heart onto your felt. | 
|  | 
| 3. Cut out your heart. | 
|  | 
| 4. Make another heart the exact same size. | 
|  | 
| 5. Lay your hearts on top of each other and sew the bottoms together. You might have to test it on a book to see how far up you need to sew. | 
|  | 
| 6. Decorate your heart however you want, and slip it onto the corner of your book! | 
Now you have an awesome bookmark! Hope you liked my tutorial!  -Lynn :)
