Iron on patches are a fun and simple way to decorate your clothes by sewing or ironing onto your t-shirts, jackets, bags, hats, scrapbook and much more. Heat-seal backing allows buyer to iron this patch onto virtually any fabric. Before applying your patch wash and dry your garment first. Set the iron to a hot cotton setting. Place the patch in the desired location and cover with a thin piece of cloth. Iron and apply firm pressure evenly on the patch for approx 30-40sec. Iron the opposite side for approx 20-30sec to reinforce. When washing turn your garment inside out and use a gentle wash cycle. The patches will iron onto most fabrics that can withstand the heat of a hot dry iron. Fabrics that may not be suitable include leather, rain wear (water-proof), highly elastic fabrics, or nylon fabrics. For materials such as these the patches can be stitched or glued.
