X Fold for Paper Airplane
We're on to the third fold of our paper airplane. First fold was this. Second fold was we came down to match. The third fold is the beginning of the diamond shape. This one is kind of tricky. You'll unfold the two folds you just made. You'll have an X. What you want to do is fold in the middle sides of the X like this and pull out the sides so it makes a point like this. Then, all you do is push down the sides and flatten. The nose isn't going to be exactly sharp. But, just push down like this. That is the next fold. So, you will have two flaps that come down like this. So, again you open the X basically making the crease on the left and right side pushing it in. Push down like this. The nose not being completely flat, but as flat as you can get it the better.
