6 15x15 cm squares of paper will result in a model measuring 9.5x9.5 cm aprox.Any paper is good, stiff papers like tant or elephant hideare the best.For copy paper smaller squares work better.

10- Fold the corner up to the point where the edges of the paper meet. Note that the marks made in step 2 also meet at this point.

5- Like this. Unfold the paper.

6- Repeat 3 and 4. Note the mark on the right side.

12- The paper should look like this.

11- Crease firmly and then unfold the paper.

13- Fold the corner up using the existing creases, the paper will not lie flat.

14- Fold the paper up, creating 2 new mountain folds and using the existing crease lines. The paper should lie flat now.

15- Like this. Note that the marks from step 2 meet again on the center. Unfold the paper.

16- The paper should look like this. Repeat steps 9-15 on the top corner.

17- Mountain fold the paper in half.

18- Focus on the left corner of the paper.

19- Fold the corner down using themarks as a reference.

20- Fold the corner up the edge to edge.

21- Fold and unfold using the edge behind as a reference.

28- Inside reverse fold using the existing crease lines.

29- Like this. Rotate the model and open it up a bit. Now we will be working on the inside.

30- Fold the corner down using the crease madein step 20. The creases made in steps 21 and 22 will align when you push the paper in in the next step. Do the same on the other side.

31- Like this. You may want to use a tool to push the paper on the mark to make sure that all the folds fall into place.

32- Look at the model from outside and start closing it using the existing crease lines. Push one side first on the mark, puting the darkened long flap under when you push the other side.

33- Put the other flap under and... 34- You've done it! Don't fold just 5 more pieces,fold a lot more and bring some happinessto someone else's day!
