If you can't find a comic book, just go with a graphic novel like I did. Don't print pictures of a comic book out from your home printer unless you have a laser printer. Photos printed from an inkjet printer, which is what most people have at home, will smear all over when you're applying the Mod Podge on top. And you need to put Mod Podge on top to seal the coasters. If not, any condensation from drinks will completely ruin the coasters. The only way you would be able to get away with printing photos from an inkjet printer is if you printed the photos then covered them in a clear contact paper. In that case, you would have to change this tutorial completely. See, the clear contact paper would be too thick for Mod Podge. So you would actually have to use a really strong glue, like E6000 glue, to stick the contact paper down to the coaster. So, it's possible. But not exactly what we're doing here.
