If you have a poster board project you did at school and you want to show everyone, you can hang it on your wall so everyone can see it. If you're going to do it, you may as well hang it well to avoid damage to your poster board.
Choose the poster board you would like to hang up. Make sure the poster board that you choose is the right size to fit on the wall.
From the top of the poster board on the back side, measure down 1/4 of the board. Draw a straight horizontal line across the board.
Make marks 1/3 of the way into the poster on either side on the horizontal line.
Place one pop tab on each of the points you made and glue them in place. Wait 15 minutes for the glue to dry before you continue. Try to move the pop tabs, and if they are firmly in place, then the glue is dry.
Measure the distance between the pop tabs. Cut a string just a little bit longer than the distance between the tabs.
Tie both ends of the string to the two different pop tabs; tie the string tight with little slack. You can now hang the poster board on the wall by either using a nail and placing the string over that or taping the string to the wall.
