+Grab your strip potentiomater, a piece of thin card, and a pencil. 
+Lightly draw round your potentiometer on the card and then use this as a guide to draw out your guitar shape. 
+(The potentiomater will be the fret board of your guitar).
+Cut out and colour in the guitar and stick down the potentiomater.
+Tape a pencil or stick to the back of the guitar to make it stiffen the fret board.
