Make a lightweight cardboard sword or shield using cardboard, paint, tape, and elastic; practice safe cutting, decorating, and attaching straps to create a wearable prop.


Step-by-step guide to make a lightweight cardboard sword or shield
Step 1
Decide if you want to make a sword or a shield and imagine how big it should be on your arm or hand.
Step 2
Place the ruler on the cardboard and draw the outline of your sword or shield with the pencil.
Step 3
Cut out the shape from the cardboard using scissors while an adult watches or helps you.
Step 4
Apply strips of tape along the edges of the cardboard to make them stronger and smooth any rough bits.
Step 5
Turn the piece over and mark where the straps or handle should go with the pencil.
Step 6
Cut two short pieces of elastic for a shield or one longer loop for a sword using the scissors.
Step 7
Tape the ends of the elastic to the marked spots on the back and press the tape firmly so the straps stay put.
Step 8
Paint a solid base color on the front of your prop with the paintbrush.
Step 9
Paint decorations and details like emblems stripes or jewels on top of the base color.
Step 10
Let all the paint dry completely until it is not tacky to the touch.
Step 11
Put your arm through the straps or slip your hand into the sword loop and check the fit then tighten or retape if it feels loose.
Step 12
Take a photo of your finished costume prop and share it on DIY.org

Help!?
What can I use instead of elastic, paint, or cardboard if I can't find them?
If elastic in step 5 is unavailable, use ribbon or a strip of old t‑shirt fabric tied and taped to the marked spots in step 6, swap cereal boxes or posterboard for the cardboard in step 2, and use markers or stickers instead of paint for steps 7–8.
My scissors can't cut the cardboard and the tape keeps peeling off—what should I do?
If scissors struggle in step 3, have an adult score the outline with a utility knife along the ruler before cutting, and if tape peels in the 'Apply strips of tape along the edges' step, press firmly, add a second layer of packing tape, or secure with a dab of white glue.
How can I adapt this activity for younger kids or make it more challenging for older kids?
For preschoolers, have an adult complete steps 2–3 (trace and cut) and use wide fabric straps taped on in step 6 with stickers for decoration in step 8, while older kids can add a glued wooden handle in step 6 and paint layered emblems and weathering details in step 8.
How can we personalize or upgrade the finished sword or shield?
After step 9 is dry, personalize by gluing craft foam or aluminum foil to the edges for dimension, adding sequins or plastic gems over painted jewels in step 8, or carefully hot‑gluing battery LED tealights behind a painted jewel to make it glow.
