I love Taiwan hot stamp patch set

Use an iron or heat press to apply the embroidery stamp to the garment. Not suitable for nylon, leather, sweaters and water-repellent clothing. If you want to increase the firmness, you can use needle and thread to sew again to prevent it from falling off. Instructions for use: Preheat the iron to a temperature above 150 degrees without turning on the steam. Place a piece of thin cloth on top of the embroidery stamp to protect the embroidery surface. Press the front side for about 20-30 seconds, press firmly without moving the iron, and use a little force. Turn the garment over and iron it again from the back. Once it has cooled completely, check to see if it is firm. Ironing time may vary depending on the fabric. If you want to increase the firmness, you can use needle and thread to sew again to prevent it from falling off.
