How to use:1. First, place the patch where you want to place it, with the hot melt adhesive side against the clothes (the adhesive cannot be torn off), preheat the iron, and iron from the front of the patch for 10-20 seconds to fix the patch in place. You can also use needle and thread to fix the patch before ironing to prevent the patch from shifting. 2. Turn the fixed patch and the clothes (or other textiles) over, and iron from the back for 30-60 seconds to ensure that the adhesive melts and the patch is firmly attached to the clothes (or other textiles). 3. Finally, iron from the front for 1-2 minutes, mainly ironing the edges and corners of the patch to ensure that the surface is flat and smooth, and perfectly integrated with the clothes (or other textiles). Note: Patches with sequins, beads, rhinestones, silk flowers, pompoms, and patches embroidered with metal threads should be ironed from the back first, and then trim the edges and corners from the front after the patch is firmly fixed to avoid damaging the sequins or other accessories on the front. Keep clothes (or other textiles) dry, and do not spray water on the patch or clothes with the iron when ironing. After the patch is ironed, it can generally be tightly attached to the clothes (or other textiles) for a long time. If the patch falls off after a period of time, or falls off after washing, it means that the iron temperature is too low during ironing, or the ironing time is too short.
