7. Turn the triangle over so that the folds you just made are underneath. The rotate the triangle so that the long edge is at the top.

8. Working only with the top layer, pick up the bottom point and bring it up so that it extends a little beyond the top of the triangle. You will notice that this causes some pulling where the fold would be, don't worry this is expected and will help give your butterfly a good shape.

9. Tuck the small triangle that is overhanging the top edge into the paper on the other side. 
10. Finally, turn your butterfly over and bring the two side towards each other. You will feel the wings fill out a little and the bottom section spread, allowing your butterfly to become a 3D shape.
