Paper Ninja Star
My 12 year old son takes karate so I thought that he would enjoy making this paper ninja star. I was right! He was completely engaged throughout the entire process and he was thrilled with the end product! The star itself is pretty cool but the fact that it slides open and closed makes it even cooler! If you want to try your hand at making this paper ninja star, continue reading for a step-by-step tutorial, complete with pictures. Good luck and I hope you have as much fun as we did!
Step 1: Cut your paper into 8 4" x 4" squares. I used 2 different colors of card stock but I think that plain paper would be easier to work with. I didn't have any colored plain paper so I opted for the card stock which is stiffer and bulkier and harder to fold but it worked.
Step 2: Fold your squares as shown above. I outlined the folded edge with a black marker so that you can see where the crease lines are. Fold your paper in half to create a rectangle as seen in picture 1 above. Press firmly along the folded edge to create a crease. Unfold. Fold your paper in half to create a triangle as seen in picture 2 above. Press firmly along the folded edge to create a crease. Unfold. Fold your paper in half in the opposite direction to create a triangle as seen in picture 3 above. Press firmly along the folded edge to create a crease. Unfold.
Step 3. Lay your paper on a flat surface so that the center line (the one created when you made a rectangle) points toward you. Fold the top two corners down toward the center line as if you were making a paper airplane as seen in picture 1 above. Fold your paper in half along the creased center line as seen in picture 2 above.
Step 4: Holding your folded paper in your hands, grab the corner that forms a right angle and slide your middle finger between the two sides to open them us as seen in picture 1 above. With your index finger, press the top corner of the right angle so that it begins to fold in on itself as seen in picture 2 above. Press that corner all the way in so that it creates a triangle as seen in picture 3 above, then fold the bottom two corners of the triangle towards each other as seen in picture 4 above. You now have a rhombus as seen in picture 5 above.
Step 5: Following steps 2-4, create 7 more rhombuses with the other squares of 4" x 4" paper.
Step 6: Take the nose of one rhombus and press it into the cavity of an alternating colored rhombus as seen in picture 1 above. Two points on the first rhombus will be sticking up past the flat edge of the second rhombus. Fold those down and tuck them into the cavity of the second rhombus as seen in picture 2 above. Pinch them together and crease firmly so that they hold the two rhombuses together. Add an alternating colored rhombus to the ones that are already hooked together, putting the nose of this third rhombus between the cavity of the second rhombus and the two folded down flaps from the first rhombus as seen in picture 3 above.
Step 7: Continue adding alternating colored rhombuses as described in step 6, creating an octagon.
Step 8: When you add your final piece and almost have your octagon completed as seen in picture 1 above, separate the two sides that form the cavity in the final rhombus and insert the nose of the first rhombus into that cavity as seen in picture 2 above. Fold the flaps down and tuck them in between the paper walls as seen in picture 3 above.
Step 9: Holding onto the opposite sides but same colored panels of your octagon as seen in picture 1 above, gently press these pieces toward the center. The paper pieces will slide towards each other as seen in picture 2 above. Rotate your octagon a 1/4 turn. Holding onto the opposite sides of the next colored panels, gently press these pieces toward the center as seen in picture 3 above. Rotate a 1/4 turn and repeat as seen in picture 4 above. Rotate a 1/4 turn and repeat.
If you have followed the steps correctly, you should have an 8 sided paper ninja star. You are now free to admire your handiwork! You can throw your ninja star, use it as a decoration or just have fun sliding the moving parts back and forth! Whatever you decide to do, I hope that you had fun creating this project!
