Can you use a hair straightener to iron on a patch?

You can use a hair straightener to seal an iron-on patch; it’s usually easier and faster than using a standard iron. You’ll need to warm it up first, position the iron patch where you want it, then clamp the warmed hair straightener over the patch on the fabric. Hold in place for about 30 to 60 seconds. Since the hair straightener is unlikely to be wide enough for all of the patch, you’ll need to move it around until all is sealed onto the fabric, each time holding the hair straightener in position for 30 to 60 seconds. If you’re concerned about the patch glue getting onto the hair straightener, fold foil around the straightener sides before heating, and remove when cooled down after use.
