Using these patches is a breeze. First, find the spot on your clothing or fabric where you want to place the patch. Then, pre - heat your iron to the appropriate temperature. Place a thin cloth over the patch and iron it firmly for a few seconds until it sticks well. Make sure to iron all the edges to ensure a secure bond. When it comes to care, avoid washing the patched area vigorously. Hand - wash gently if possible. If machine - washing, use a gentle cycle. Store the patches in a dry place when not in use to keep them in good condition.
