Select your comicbook page, and cut it so you have an excess of material.
Then, slowly, cut the material down so it fits your particular notebook.
Next cut your iron on vinyl to fit the comicbook cut out.
Iron on the vinyl as per instructions on the box.
This step was a bit of trail and error for me. I cut it too small a few times
(I learned this process thanks http://www.readymade.com/projects/fold_a_wonder_wallet
, so yes reading that would be a good help.)
