You will need:
•Duct tape/washy tape
Take your notebook and if it already doesn't have a design on it, you can measure it with your ruler and cut it out, and you want to put on your Mod Podgue on the back and before you do that, cut out some holes on the side with your hole puncher. Then, once you have that glued on, you can add on another layer of Mod Podgue with your painting sponge on the top if you want to make it much more nice and shiny, as well as secure the edges. Then you can design/customize it with markers and duct tape/washy tape to make it much more cute and girly.
Hope you guys found this helpful!
