For this instructable you will need the following things...
. 36 by 17 inches styrofoam
. paint of your option
. pencil and eraser
. black marker
. sharp knife
. 6 1/2 inch nails
. 3 thick and 3 thin elastic bands
Step 2: Step 1
On your 36 by 17 inches piece of styrofoam draw a shape of a guitar with a pencil. Then outline the shape with a black marker to help you see the shape better.outline the whole guitar until you can see it clearly. After you outline it take your knife and start cutting it.I'd prefer putting a piece of wood under it so you dont cut anything on the floor or carpet.Cut the guitar very slowly so you don't end up cutting yourself. You should have an adult nearby when you are cutting. After your done cutting the shape just cut out the big chunks on the sides of the styrofoam. If you need help drawing the shape you can copy mine.
Step 3: Step 2
After your done cutting the styrofoam and make it perfect we move on to the next step which is painting. Personally I like red so I painted mine red but you have your option. When your painting be sure not to get it on your hands or lick it. Try to paint the top and the sides but you could paint the bottom too. After your done painting leave the guitar near somewhere hot or nea a heater. It will take 2-3 hours for the paint to dry off.
