Introduction: How to Make a Cardboard Knight Helmet

Hello!, thanks for checking out my first project! I made a cardboard helmet using only supplies from around my house. I hope you give it a try in your spare time! Thanks again! Enjoy!



-2 pizza boxes

-Extra cardboard (if needed)

-Hot glue

-Duck tape


-Scissors and/ or exacto blade


-Pencil/ Pen (try to use a pencil in case you need to erase)

Step 1: Step 1: Cut Out the Top

Cut a circle in the pizza box that has a diameter of 7.5-8 inches, I used a plate to trace out the circle. I'm 14 years old and the helmet fits me about right so you can go smaller or bigger depending on the size of your head. Cut it out in a corner and feel free to use a dirty section of the pizza box as it will be covered with duct tape anyways.

Step 2: Step 2

Now you should have a cardboard disc. Layer duct tape over one side and go on to the next step.

Step 3: Step 3: Cutting Out the Main Body

Now you will need to trace and cut out two sheets of cardboard. One of them should be 8x13 inches and the other 10.5x13. Now lay both sheets flat with the long sides horizontal. Next, flip both sheets upside down. Align your ruler horizontally on the back of the sheet and mark it in 1/2 inch increments, do this to both sheets.

Step 4: Step 4: Creasing

Now we will crease the sheets to get the desired curve. Scout around your house and find an object that can be used to crease the cardboard (for example you could use the blunt tip of a butter knife). Once you find something, use your tool to create diagonal creases along the marks you made in the previous step. Use your ruler to keep your creases straight. Don't use too much or too little pressure. After this, carefully bend the cardboard along the creases to get a nice curve.

Step 5: Step 5

Now flip the top of the helmet upside down and take the smaller sheet and attach it the top of the helmet we made earlier. Use\pieces of duct tape to attach the two together. Look at the image above to see what your helmet should look like so far. Once you've done this, take the other sheet and hold it against the upside down helmet. Do this to find out how much you need to shorten it. Trim of 1 segment at a time until the second sheet can fit snugly in the space, I had to trim off 3 segments.

Step 6: Step 6: the Eye Holes

Now it's time to draw and cut out the eye holes. Take the sheet and mark the bottom center point for reference. Then use the measurements given in the image to draw and cut out the eye holes.

Step 7: Step 7

Now use the measurements in the image to mark and cut the face of the helmet. After this you can attach this to the rest of the helmet using pieces of duct tape and hot glue. The helmet is now done and ready to wear ut the final few steps will just be decorating it. If you don't like my design, you can try out something different for the previous and next couple steps.

Step 8: Step 8: Decorate

To finish it off, I used some more cardboard, duct tape, and hot glue to decorate the face of the helmet.

Step 9: Thank You!

Once again, thank you very much for checking out my instructable. I apologize if it isn't the best quality as I'm still getting the hang of it. I hope you had fun doing this project and enjoy your new helmet! Also, please vote for me in the Glue and Tape Speed Challenge if you enjoyed this! Thanks!
