I used sheet music the first time I made this; however for the tutorial, I will use a few solid colored pieces of paper so it will be easier to follow. You will need 5 sheets of paper in total. (a)20cm x 20cm, (b), 15cm x 15cm, (c)8.5cm x 8.5cm, (d)8.5 cm x 8.5cm, (e)for the trunk 15cm x 15 cm

Let's make the trunk of the tree first. I'm using my dark green sheet of paper which is 15cm x 15cm.

Fold in Half. Make sure that the colored side is facing out...then unfold.

Now fold in half the other way...then unfold. Turn the paper over now so that the green square is facing up.

Now...fold corner to corner, shown here. :) Now turn over so that the white side is face up.

Place your finger over the center of the square, shown here, and simply press down. This will allow the corners of your square to "pop" up.

Now Grasp two corner together as shown....

As you are holding those two corners in place, gently bring up the other two corners, so that all 4 corners are brought together as shown. Lay project flat on your desk. You should have a flat small square.

Now raise one of the flaps, stick your finger inside which will create this cone effect. :) why does this sound bad? LoL...

Then simply squash it flat, shown here. Make sure it's centered nicely. Repeat step 9 and 10 on the remaining 3 sides.

This is what you should have now. :)

Turn the front flap, and back flap over shown here...

Now, take that front flap....

...and tuck it inside...like this. Repeat this step for the back flap as well. :)

This is the top view of what you should have so far. Now, simply tuck in the side flaps....

...Just one more flap to tuck in, and then we will be done with the trunk!

All tucked in...good job!

Congrats! Here is your trunk. Now simply add a glue dot to the front and back, and set aside. View step 19.

There's the placement of the glue dot. Add one to the back, and set aside. Now...lets start with the bottom layer of the tree!

Start with your 20cm x 20cm size sheet...I'm using light green copy paper. It's green on BOTH sides...

Fold in half, then unfold.

Fold in half the other way, then unfold. Turn paper over...

Fold corner to corner...just like we did with the trunk. Flip sheet over...

Place finger in the middle of the sheet, and press down to "pop" up the corners.

Grasp two of the corners....

Bring up all four corners together. :)

This is what you should have now...Place on your desk flat.

Bring one flap up to the top point of the module, press flat.

This is what you should have so far. Do not unfold this crease.

Fold flap over, and repeat steps 28 and 29 on the remaining three sides. :)

This is what you should have now.

Start bringing the tip down.

It's very important to place your fingers the way I've got mine.

You want to create this "M" shape between the flaps.

Then sandwich that "M" shape between the two flaps like this. Press firmly. :)

This is what it should look like. Repeat steps 32 to 35 on the remaining three sides.

Aerial View...lol of all the sides completed for this module. Now lets place it on the trunk! :)

Insert the bottom of the trunk into the tree. Careful of the glue dots. When it's where you want it, make contact with the glue dots.

Awww...it's kinda cute already! LoL

I used a deeper green to show the next layer of the tree. This one is the 15cm x 15cm sheet of paper, repeat the EXACT same steps (steps 20-37) for this layer. Make sure you add a couple of glue dots to the bottom layer first, and then position the next layer on top of it. Now lets go to the small top layer.

Here's the top layer. Use the 8.5cm x 8.5 cm paper for this. EXACT same steps. Just follow steps 20-37 Again. Now for the tippy top!

Use the other 8.5 cm x 8.5 cm piece to make the tippy top. Follow the TRUNK instructions, steps 3-12 to create this piece. Make sure there are a couple of glue dots on the small layer before placing the tippy top on! Voila!

You have done it! Congrats! I hope you have enjoyed this tutorial!
Lanie. :)
