1) Divide your paper into an 8x8 grid perpendiculary and in 16ths diagonally.
Then make two mountainfolds on the 3/8ths and 5/8ths creases as shown.2) Here's what it should look like. Fold the ends inwards, so basically you end up with an open-box shape. See pic three for clarifaction.
3) So good so far?
4) Repeat the same process. The sides squish in.
5) Here's what you should end up with. Repeat step 4 along this row.
6) This is the first row finished. Turn your model to the side for step 7.
7) Essentially you're pulling up the sides. Don't pay attention to the direction the creases are going in the picture, just stick to the color of the crease lines and you'll be fine. You're performing reverse folds here.
8) Here's a close-up of step 7, with the creases half-folded in the proper directions.
9) Just mirror what you have already folded on the other side.
10) Again, from the side, continuing with the pattern. Lots of reverse-folds.
11) Here's one side finished. Practice steps 7-12 on the other side. By now you should get the idea.
