Origami 8-pointed Ninja Star

This is another variation of the origami 8-pointed ninja star. This one has a solid center. The other has a hollow center. We can't decide which one we like better!

Origami 8-pointed Ninja Step 1: Start with a 6 inch x 6 inch (15cm x 15cm) square origami paper. Cut paper into 2. We'll use half of the square paper for one unit.

Origami 8-pointed Ninja Step 2: Fold your now rectangular paper in half on the horizontal axis. Crease well.

Origami 8-pointed Ninja Step 3: Fold paper in half on the vertical axis. Crease well and unfold.

Origami 8-pointed Ninja Step 4: Make 2 diagonal folds, one on each end. Note the direction of the folds.

Origami 8-pointed Ninja Step 5: Make 2 more diagonal folds. Once again, notice the direction of the folds.

This completes your first unit.

Origami 8-pointed Ninja Step 6: Cut a square paper of another color into two. You could use the same color paper as the first unit but it looks better with a different color.

Fold the rectangular paper in half on the horizontal axis. Crease well.

Origami 8-pointed Ninja Step 7: Fold paper in half on the vertical axis. Crease well and unfold (Forgot to take photo for this step!).

Then make a diagonal on the right corner.

Origami 8-pointed Ninja Step 8: Make 2 diagonal folds. Note the direction of the folds.

This completes your second unit.

Origami 8-pointed Ninja Step 9: Flip the first unit (orange) over and rotate the 2nd unit (yellow)so that they orientated as shown in the photo below.

Origami 8-pointed Ninja Step 10: Place the yellow unit over the orange one.

Origami 8-pointed Ninja Step 11: Fold the orange tips over and tuck them under the yellow layer. This step is the same as when assembling the original ninja star.

Origami 8-pointed Ninja Step 12: Flip paper over.

Origami 8-pointed Ninja Step 13: Fold the left tip of the yellow unit over and tuck it into the orange unit.

Origami 8-pointed Ninja Step 14: Make a mountain fold as shown on the right side of the yellow unit.

Origami 8-pointed Ninja Step 15: Fold point A to point B. Crease well and unfold.

This completes one assembled unit.

Origami 8-pointed Ninja Step 16: Repeat Steps 1 to 15 and make a total of 4 assembled units.

Origami 8-pointed Ninja Step 17: Flip the assembled units over and orientate the two units as shown below.

Origami 8-pointed Ninja Step 18: Place the bottom unit over the top one.

We're going to "hook" the square end of the top unit onto the bottom unit.

Origami 8-pointed Ninja Step 19: Repeat Step 18 for the other 2 units to complete the modular origami.

Here's the completed origami 8-pointed ninja star!
