1. How to Make Your Flipbook:
Take your 3 sheets of purple and 1 white paper and stagger them so that there is enough space between two sheets of paper for you to write something. About ¼ inch. Put the two colors that are the same on top.

2. Now, fold the top of your papers so that they overlap to make 4 more flaps. You want your top flap to be as big as you can make it to maximize the space you have on the back of it. Staple them at the top. You should now have a flipbook!
