This is a very simple, easy paper airplane for beginners.
Step 1: Step 1: Get the Paper
Find your self a piece of paper. Normal printer paper (8.5 by 11) works just fine.
Step 2: Step 2: Fold in Half
Fold the paper half way long ways. The fold won't be perfect but that's okay. You're doing great! :D
Step 3: Step 3: Making the Triangle Folds
Fold the corner of one side of the paper into the crease to make a triangle. Do this to both halves of the long crease from step 2.
Step 4: Step 4: First Part of Making the Wings
Have the view seen in the first picture. From there fold one of the creases again to the bottom of the plane making a type of wing (Picture 2). Do this to both side and what you should get is a plane with large triangle wings when the wings are up (Picture 3).
