How to remove wrinkles from flags (Polyester or Nylon)?

A:  You can use a cool iron.

The most commonly used fabrics for flags are polyester and nylon which can be ironed with your standard home appliances.

• Begin by making sure that your iron’s internal reservoir has water. If not, fill it up.
• Then set the iron to the lowest heat to avoid damaging the flag material.
• While it heats up, stretch one end of the flag over the ironing board, allowing the remainder of the flag to hang down the back of the board.
• Before applying the iron, smooth the flag with your hand to remove any wrinkles.
• Iron the flag slowly back and forth with medium pressure until they flatten and relax.
• Once the wrinkles are removed, hang your garment up and let it cool.
