You can build a wearable football helmet from paper, cardboard, and a few household supplies in about two to three hours. The basic approach uses a balloon as a mold, paper mache for the shell, and cardstock for the face mask. It won’t protect your head on a field, but it works great for costumes, school projects, spirit week, and kids who want to look the part on game day.
What You’ll Need
- Balloon: A standard round latex balloon, inflated to roughly the size of the wearer’s head.
- Newspaper or scrap paper: Torn into strips about 1 to 2 inches wide. Newsprint is ideal because it’s thin and conforms easily to curves.
- Flour and water: For the paste. One cup of all-purpose flour mixed with two cups of water.
- Cardstock or light cardboard: For the face mask and any reinforcing ribs. Cereal boxes work well.
- Tape: Duct tape is strongest, but masking tape or clear tape will do.
- Acrylic paint: For your team colors.
- Gesso or Mod Podge: To seal the shell before painting.
- Scissors, marker, and a mixing bowl.
Mix the Paper Mache Paste
The classic flour paste is cheap, strong, and made from two ingredients. Pour one cup of plain flour into a bowl, then gradually add two cups of water while stirring. Keep mixing until the lumps are mostly gone. The consistency should be like thin pancake batter. If it’s too thick, add a splash more water.
You can also make this on the stove by gently heating the mixture and stirring continuously, which dissolves the flour more completely and creates a slightly smoother paste. Either version dries hard and holds its shape well. Flour paste actually creates a stronger bond than most white craft glues, and it’s biodegradable, so cleanup is easy.
If you prefer not to use flour (or worry about mold in humid climates), a 50/50 mix of white school glue and water works as a substitute. Flour is cheaper and slightly more rigid when dry, though.
Build the Helmet Shell
Inflate your balloon until it’s slightly larger than the wearer’s head. Set it in a bowl to keep it stable while you work. Dip a strip of newspaper into the paste, run it between two fingers to remove excess, and lay it across the top half of the balloon. Overlap each strip by about half its width so there are no gaps.
Cover the entire upper hemisphere of the balloon, extending down past the midpoint on the sides and back. Leave the front more open where the face will be. You want the coverage area to look like the profile of an actual football helmet: lower in the back, curving up and away from the face in front.
Apply three to four layers for a shell that’s firm enough to hold its shape but still lightweight. Let each layer dry for 30 to 45 minutes before adding the next one. Rushing this step leads to a soggy shell that sags. If you’re short on time, a hair dryer on low heat speeds things up. The full shell typically needs overnight drying before it’s ready for the next steps.
Shape and Trim the Opening
Once the shell is fully dry and rigid, pop the balloon and pull it out. Try the shell on the wearer’s head and use a marker to trace where you want the bottom edge to sit. On a real football helmet, the opening is roughly oval, dipping lower behind the ears and higher across the forehead.
Cut along your marked line with scissors. Paper mache cuts cleanly when dry, so take your time and smooth out any jagged spots. If the edge feels flimsy, fold a strip of duct tape over it like binding on a quilt. This reinforces the rim and gives it a cleaner look.
Add the Face Mask
Cut the face mask from cardstock or a piece of cereal box cardboard. A simple design is two or three horizontal bars connected by a vertical strip down the center. Measure the opening of your helmet’s face area first, then cut the bars about half an inch wider on each side so they have material to attach to the shell.
Bend the ends of each bar to match the curve of the helmet and tape them in place with duct tape. For a sturdier connection, use small tabs of paper mache paste and newspaper over the attachment points and let them dry. If you want the bars to look rounded like a real face mask, roll thin strips of cardstock into tubes before attaching them.
Reinforce Weak Spots
Cardstock is significantly thicker and more tear-resistant than newspaper, so use it anywhere the helmet feels thin or flexible. Cut strips about an inch wide and paste them along the inside of the shell from front to back like ribs. Two strips running from the forehead to the back of the neck, plus one across the crown from ear to ear, will add noticeable stiffness.
Corrugated cardboard (from a shipping box) is even stronger. A single strip of corrugated cardboard along the interior crown makes the top almost rigid. Just make sure to paste over it with a layer of newspaper so everything bonds together.
Seal and Paint
Raw paper mache absorbs moisture, so painting directly on the surface can cause warping and bubbling. Seal the entire exterior with gesso first. Gesso dries hard in about 15 minutes per coat, and two to three thin coats create an excellent surface for acrylic paint. If you don’t have gesso, Mod Podge works as a sealer too, though it dries with a slightly softer finish.
Once sealed and dry, paint your team colors with acrylic craft paint. Start with the base color and let it dry completely before adding stripes, logos, or numbers. Painter’s tape helps you get clean lines for stripes. A fine-tipped brush or paint pen works well for small details like a team logo. For the face mask, painting it a contrasting color (gray or white is classic) before attaching it gives the cleanest result.
A final coat of Mod Podge over the painted surface adds a slight gloss and protects the paint from chipping.
Pad the Interior
A bare paper mache shell will slide around on your head and feel uncomfortable within minutes. Adding simple padding solves both problems. The easiest option is cutting strips from an old yoga mat or mousepad and hot-gluing them to the inside of the helmet. Four to six strips, each about one inch wide and three to four inches long, positioned around the crown and sides, will hold the helmet snugly in place.
Upholstery foam (the kind used in couch cushions) is another common choice. Half-inch-thick foam is soft, lightweight, and easy to cut to shape. EVA craft foam sheets from a craft store work just as well and come in convenient pre-cut sizes. Hot glue holds all of these materials securely to the paper mache interior.
If you don’t have any foam on hand, folded washcloths or strips of bubble wrap taped to the inside will get you through a costume event.
Optional Details
A chin strap turns the helmet from a prop into something that actually stays on during movement. Cut a strip of fabric or ribbon about 12 inches long and staple or tape each end to the inside of the helmet near the ear area. Elastic works especially well since it stretches to fit.
For ear holes, mark circles on each side of the helmet where your ears sit and carefully cut them out with scissors or a craft knife. A ring of duct tape around each hole prevents tearing.
To add a center ridge (the raised strip that runs front to back on many helmets), roll a sheet of newspaper into a tight tube, bend it to match the helmet’s curve, and paste it along the crown. Two layers of paper mache strips over the top blend it into the shell seamlessly.
