The Rock Paper Scissors costume is a strong three person group idea. These DIY examples will help you plan. This is not a last minute build. The more time you spend, the better it looks. Recruit two friends to be the full set and to help with the build.
How to make a Rock Paper Scissors Costume
The Rock Costume
Materials
- Foam rubber, two sheets about 50 by 50 cm, 7 cm thick
- Scissors or utility knife
- Spray paint, light gray and dark gray
- Two straps of black elastic or webbing
Steps
- Cut two square panels for front and back. Round and notch the edges for a rough stone shape.
- Paint outdoors or in a ventilated area. Coat both panels with light gray. Let dry. Add light passes of dark gray for texture.
- Cut two parallel slits near the top and two near the sides on both panels. Thread elastic to make shoulder and side straps. Adjust to fit.
The Scissors Costume
Materials
- EVA foam sheets, two red for handles, two gray for blades
- Paper template, scissors, contact cement or hot glue
- Elastic or webbing for shoulder straps
Steps
- Sketch one half of a large scissor on paper. Mirror it to form a full scissor. Transfer to EVA.
- Cut two red handle layers and two gray blade layers for front and back.
- Glue layers to build a rigid front and back. Add a small circular hub where blades cross.
- Join front and back with shoulder straps. Add side ties if you want a tighter fit.
The Paper Costume
Materials
- White EVA or poster board, two panels
- Markers, blue and red
- Cord or elastic for shoulders and sides
Steps
- Cut two large rectangles to cover front and back.
- Draw blue horizontal lines and a red vertical margin line. Add three black binder holes on the left edge.
- Punch small holes at the shoulders and sides. Tie panels together with cord so wind does not lift the panels.

Build tips
- Test fit early. Trim edges to keep arm movement clear.
- Keep finishes matte. Gloss can glare in photos.
- Label inside straps Rock, Paper, or Scissors to avoid mix ups.
