Simple steps to follow:
Step 1: Remove patches from the envelope.
Step 2: Choose the right size patch for the hole in your garment (leaving 1 cm of material around the hole)
Step 3: Turn Garment inside out (the patch is designed to bond to the interior layer of fabric)
Step 4: Heat iron to the highest setting (polyester)
Step 5: Place patch over the hole (glossy side down)
Step 6: Place a scrap piece of fabric between the iron and the patch (to avoid damaging your iron)
Step 7: Apply iron to patch for 10 seconds.
Step 8: Avoid wearing the garment for 10 minutes before use.
