In addition, but not shown in picture:
Some sand paper or flexible sanding block
Damp paper towels to wipe glue from your hands throughout
I prefer to use older comics that are thin and matte like newspaper. They tend to soak up the glue better than shiny comics and are thinner so they mould to corners, curves and edges better. But shiny comics do work if that is all you have.
You can use Mod Podge but for this project I used Deco Mache which I really love.
