So there's this story...

So there's this story of this Irish Dude going to a Festival and he is comissioned to create a banner of 14 leprechauns. On his way there the wind blows the banner out it gets tattered and ripped but he puts it back into one large banner. To his surprise, there are now 15!!!!!

Try to figure it out. If you dont believe me, print the image out and cut it along the lines.
