Fix a misplaced fold. If you messed up and want to refold any of your plane, be sure to smooth out the old crease as much as possible. Be sure and crease the new fold sharply by running your fingernail along the crease.

(Don't fold it inwards--it should meet the external edge of the center crease.) This will establish one wing. Hold it down with one hand and crease. Take care that you don't line up the rear, unfolded tip of the wing with the center crease. It's the diagonal edge that needs to line up with the external center crease.   Flip the airplane over and repeat the wing fold. Fold the diagonal edge over so it's even with the center crease. Now you should have the two wings. Skip to Step 4 for flight instructions. Method 2 - Step 1
