How to Make a Captain America Shield from Cardboard
Cut a 24–30 inch cardboard circle, paint or paper the red-white-blue rings and star, then glue on arm straps. Knife, mat, glue.
What You'll Need
- Large corrugated cardboard sheet
- Red, white, and blue acrylic paint (or construction paper)
- White paper for star template
- PVA craft glue or hot glue
- Elastic straps or webbing (2 pieces)
- Craft utility knife
- Self-healing cutting mat
- Metal ruler 18 inch
- HB pencils (pack)
- String for circle drawing (or large compass)
Use a box you already have; buy paint or paper only if you need the colors.
You’re cutting one large cardboard disk (24–30 inches / 60–75 cm), marking four equal rings, coloring them red–white–blue with a white star in the center, then gluing two straps on the back. Plan 2–4 hours including dry time. Moving-box cardboard works; double-layer if you want it stiffer.
Cut on a mat, blade away from your hands. Kids need an adult on the knife.
Cut the cardboard circle
Pick diameter 24–30 inches (60–75 cm); smaller for a child. Poke a center hole. Tie string to a pencil, set length to the radius, and draw the circle. Cut with several light knife passes. Sand or trim rough edges if needed.
For a sturdier shield, glue two cardboard sheets together and let dry before you cut the circle.
Mark four equal rings
Radius ÷ 4 = one ring width. From the center, draw circles at 1×, 2×, and 3× that width. Innermost disk = blue. Next ring = white. Next = red. Outer ring (to the edge) = red.
Paint or paper the colors
Paint method: blue center, white ring, two red rings. Let each color dry before the next.
Paper method: cut a blue center disk, a white ring, and red rings to match the marks; glue from the center out, smooth bubbles.
Add the white star
Draw or print a five-point star that fits inside the blue disk with a thin blue border. Cut it from white paper and glue dead center, or trace and paint white.
Glue on the arm straps
On the back, position two elastic straps so a forearm slides through (one near the top of the arm, one lower). Hot-glue or staple them firmly. Let all glue and paint cure before wearing.
Pad the straps with a scrap of fabric or foam where they hit the forearm if they dig in.
