how to make a penalty flag

Creating a penalty flag, often used in American football, can be a simple DIY project. Here’s how you can make a basic penalty flag:

Materials You’ll Need:

  1. Yellow Fabric: You’ll need a piece of bright yellow fabric, like felt or flannel, approximately 12 inches by 12 inches (30 cm by 30 cm).
  2. Thread: Yellow or a matching color to sew the flag.
  3. Scissors: For cutting the fabric.
  4. Sewing Machine (Optional): You can sew the flag by hand if you don’t have a sewing machine.
  5. A Wooden Dowel or Stick: About 6-8 inches (15-20 cm) long for the flag’s handle.
  6. Hot Glue Gun and Glue Sticks: For attaching the flag to the dowel.


  1. Cut the Fabric:
    • Cut the yellow fabric into a square, approximately 12 inches by 12 inches (30 cm by 30 cm).
  2. Fold the Fabric:
    • Fold the fabric square in half diagonally to create a triangle.
  3. Sew the Edges:
    • Sew along the two open edges of the triangle, leaving the folded edge open. This creates a pocket where you can insert the dowel.
  4. Turn It Inside Out:
    • Carefully turn the flag inside out through the open end so that the seams are hidden on the inside.
  5. Insert the Dowel:
    • Insert the wooden dowel or stick into the open end of the flag. Push it up to the point of the triangle, so it fills the flag completely.
  6. Secure the Dowel:
    • Use a hot glue gun to secure the open end of the flag around the dowel. Apply a thin line of hot glue along the edge of the fabric and press it closed around the dowel. Be careful not to burn yourself with the hot glue.
  7. Trim Excess Fabric:
    • Trim any excess fabric from the open end of the flag, leaving a neat edge.
  8. Optional: Add a Handle Grip (Optional):
    • You can wrap the top end of the dowel with a small piece of foam or fabric to create a handle grip for comfort.

Your DIY penalty flag is now ready to use. Wave it to indicate a penalty during your football games or as a fun prop for parties and events. Remember that while this homemade flag can be a playful addition to your games, official penalty flags used in professional football are typically made to strict specifications for visibility and consistency.
