See how to make the Sonobe Unit before you follow the directions below.

You are going to need 30 units to make this star.

Start with three units. You slide the flap of one unit into the pocket of the next unit.

As you push then together, they should make a nice corner for the start of your cube.

You should be able to create five of these corners (or pyramids) attached to each other.

As you put the rest of the star together, you will have 15 more corners that will appear.

See how to make the Sonobe Unit before you follow the directions below.

You are going to need 12 units to make this star.

Start with three units. You slide the flap of one unit into the pocket of the next unit.

As you push then together, they should make a nice corner for the start of your cube.

You should be able to create four of these corners (or pyramids) attached to each other.

As you put the rest of the star together, you will have 4 more corners that will appear.

See how to make the Sonobe Unit before you follow the directions below.

You are going to need 6 units to make the Cube.

Start with three units. You slide the flap of one unit into the pocket of the next unit.

As you push then together, they should make a nice corner for the start of your cube.

Add a fourth side, by placing a fourth unit’s flap into the pocket of one already attached to the corner. Slide the flap that is hovering over the new unit into the pocket of that unit.. You should now have two corners of the cube.

Do the same with the fifth side. This time 3 flaps will fit into 3 pockets. Now you have four corners of the cube.

Finally the last unit will slide its flaps into the pockets of the cube. The two flaps that are left will fit into the pockets of the sixth Unit. Now you will be able to count all eight corners of the cube.

To make the Sonobe Unit, I used a normal sized 3-inch Post-it note.

Fold the Post-it note in half. I like to have the sticky side at the top and on the inside of the fold when I fold it. This will allow the sticky side not to get in the way later on when I try to put together multiple units.

Open the fold you just made, then fold the right side in to meet the center crease.

Do the same to the left side.

Open the right side and fold the top, right corner to meet the crease furthest to the right.

Rotate the Post-it note and fold the top right corner again, just like you did in the last step.

Refold the two sides towards the center crease.

Fold the Top left corner so the top edge meets the right edge.

Tuck that same corner under the right flap to look like the picture above.

Rotate the Post-it note and do the same thing to the opposite side.

Flip the whole thing over and fold the top corner down so there is a diagonal across the center of the Post-it note. Do the same thing to the bottom corner.

Finally fold the diamond along the diagonal made by the two corners. Your Sonobe Unit should look like the image above.

Now You can make the following designs:

<> 
• The Sonobe Cube
• The Sonobe 8-Point Star (octahedron)
• The Sonobe 20-Point Star (icosahedron)

To make this little Christmas ornament, I used post-it notes. To make it more colorful, I used 3 different colors of post-it notes. I went around the office and found 3 different colors on my co-workers’ desks.

The first step is to fold the post-it from corner to opposite corner. Ideally you will want the sticky part to be on the inside.

Next, fold the newly formed triangle in half. This will make a crease to prepare you for the next step.

Fold the outside corners of the triangle up to meet the top corner. The bottom edges of the triangle should meet the crease you made in the previous step.

You should now have a diamond shape with two corners flapping at the top.

Turn the whole thing over and peel the top flap back. It will be sticky because of the post-it note.

Fold that same flap back onto itself where the corner meets the center of the diamond.

With the corner between you fingers, you pull the flap up to where the crease you made in the previous step meets the crease along the center of the diamond.

Now fold the corner back reversing the crease you made two steps ago.

Again you will want to fold the flap where the corner once again meets the center of the diamond.

Now find the other two post-it notes and do the exact same thing to them. You should have three diamonds with an interesting pattern along the center of them and two flaps on the back of each. Again different colors will make fore a more interesting ornament.

Take the two flaps of one of the diamonds and slide them under the design of the second diamond. The flaps should fit snugly all the way to the point of the second diamond.

The object is to get the flaps of all three diamonds under the designs of their neighboring diamonds.

Once you get them all together, they should look similar to the image below. Find two paperclips and link them together. This is what we will use to hang your ornament.

Loosen the diamonds just enough to get one of the paperclips into the shape. The paperclip that is outside of the shape should be bent just enough to make a hook.

Now you are ready to hang them on your tree or your neighbors’ cubicle. If you have enough time on your hands, make 100 of them and hang them all over your boss’s office. OK that might go a little far, but it’s a thought.

You can use those price tags on a string if you can find them in the store. As for me, the paperclips work great for an ornament that will most likely only make it though one Christmas.

The following steps correspond to the images above. Read the images top left first, top right second, second left third, second right fourth and so on.

25. Fold the opposite corner the same way completing the paper airplane-like fold.

26. Grab the side corners on the front and make them touch. Then grab the side corners on the back and make them touch. There should be two legs that extend downward.

27. Grab one of the legs and pull it outward, allowing the side to open slightly so you can invert the fold to make the neck of the crane,

28. Do the same thing to the other leg to make the tail of the crane.

29. Invert a small section on the neck to mimic the head of the crane. If you did it right, the nose should be a perfectly sharp point.

30. Bend the center flap down to create the wing, then turn the bird over.

31. Bend the other flap down to create the other wing.

32. The last step is to get rid of the point on the cranes back. If you pull out on the sides of the point, you will be able to press the point inwards, hiding the point inside the crane.

That’s it. You made your own crane. I hope my instructions were easy enough to follow. The pictures should have helped.

The following steps correspond to the images above. Read the images top left first, top right second, second left third, second right fourth and so on.

17. Fold the opposite corner the same way completing the paper airplane-like fold.

18. Grab the bottom corner and, like the other side, allow the two flaps you just folded open up, and pull the corner over the top point, creasing it about three-fourths of the way up the diamond.

19. Now you can flatten the sides against the second stretched diamond.

20. Take the two side corners in the front and make them touch, then take the two back corners and make them touch. You should now have something that looks like a dog with its ears pointing strait up.

21. Take one corner and fold it towards the center crease, adgain like you were folding a paper airplane.

22. Do the Same thing to the other corner.

23. Flip the whole thing over. We are going to do the same thing to the other side.

24. Fold the corner towards the center crease like you were folding a paper airplane.
