Step 3: How to Make a 3D Mario Box Part 3
When Ironing the sides make sure you go in a circle motion, Only iron for 30 seconds!
* DO NOT OVER IRON!*
if you over iron the beads will not lock together! you DONT want the holes to close completely,
once thats done flip it over and iron again for 10 seconds just to give it strength!
Place all the pieces under a Flat heavy surface so they do not bend! this part is very important!
