Everyone's made a paper aeroplane before and we've all been disappointed when they barely fly. Well, we've found a website that has 40 different paper aeroplane designs each with detailed step by step instructions. Fold N Fly even tags each design to show if it's best for distance, airtime and acrobatics. If you're not good at following instructions or folding in a straight line then don't worry there's even a printable line guide for each design. There's no chance you lose your next paper aeroplane contest so get on and challenge the rest of the office. We'd love to see any of your attempts at making these designs!
