Here is how to make your own trading card boxes using an old box. They can be made to fit magic, poker, Pokemon, or any other cards that you have a box for.
You will need a pen, some paper, a razor, and a cutting board. A ruler is also handy.
Step 2: Make an guide to trace
Unfold your box and trace around all the edges. Make sure to mark where you're going to fold it also.
Then cut out the paper "mold". Make sure not to cut your fold marks.
Step 3: Trace your guide onto cardboard
Sadly on this one the cool dragon is too far off center so I chose the minitar.
Step 4: Cut out the cardboard
Always cut away from your self, and I like to also cut away from the center so if the knife slips it doesn't ruin the box.
