This is a super simple way to make a a customized magnet using hot glue :D
Step 1: Material
-Graphics (Magazine, Comic Book, Prints, etc)
-Mold (here I'm using a bottle cap)
Step 2: Trace the Bottle Cap Onto the Graphics
The title says it all :D Simply trace the bottle cap onto the graphic of your choosing.
Once you're done tracing, simply cut it with scissors.
Step 3: Place the Graphic Into the Cap
Put the graphic into the cap, faced down. The blank side/ the side you don't want should be facing you.
Step 4: Pipe in Hot Glue
Fill the cap with hot glue and let it dries.
Step 5: Attach Magnet
Pipe some more hot glue onto the middle in order to stick the magnet on.
Step 6: Remove Hot Glue From Cap
This part is a little tricky, I used a utility knife to peel it out, but you can use anything that has a sharp edge but flat surface such as a knife.
*When I was able to remove the hot glue, the graphic was a little distorted at the edge from the constant poking of the utility knife, so I cutaround the edge and made it into a smaller circle with the scissors. This is pretty easy since hot glue is relatively soft to cut into.
