Have a glue gun, some shiny pennies and time? Bam! Do a fun accent wall! There are really no instructions other than to use quality glue sticks and a full size glue gun. I think it gets hotter and holds stronger than the mini's. Also, start with a straight line and move in the same direction. The pennies will fit better when you don't change direction. If you start working horizontally, you must finish that way. You can't switch and go vertical mid project. Your pennies will not fit! Learned that the hard way!
