Many people ask how to apply Hot Fix Swarovski Crystals to a product. A regular household iron can be used, but might not provide the correct heat temperature and pressure for adhesion of the crystals. The best option for a professional look is a heat press machine. These can be purchased from several online vendors and, depending on features and size, the price begins around two hundred dollars for an economy heat press. Heat press machines have adjustable temperature controls and apply a consistent even pressure to your designIt is very important to test your fabric and crystals to determine the correct settings for your heat press machine before you hot fix the crystals to your final project. I recommend using a Teflon sheet on top of the crystals and the heat plate so the plate and crystals do not get scratched and you don’t get any glue on the heat plate. Another Teflon sheet should be used inside your item or garment so that you don’t accidentally glue the front and back together. It will take some trial and error to see what works best for you and the design you are creating.
