Iron On Vinyl Decals can be easily applied to any face mask, shirts, book bags, etc. Many colors available to choose from, if you do not see the color you want available, message me. Instructions: Fabrics That May Or May Not Be Used! YES: cottons, cotton blends, wool, silk, velveteen, velour, denim (the softer the better), t-shirts and sweatshirts are probably your easiest fabrics; lycra, slinky (a little trickier, but possible), cotton sweaters are easiest. Always test fabrics if you’re not sure, read the garment hang tag. NO: nylon jackets, velvet, acrylic, leather, vinyl, trigger (fabrics with a finish). Don’t forget to read the hang tags. Always iron on a hard, flat surface (no padded ironing board). Lay out your garment. Place the sticky side down onto fabric. If not in the desired place, you may pick up the design and place it again and again. Cut it apart, change it, nothing is permanent until you press it on.Put the pressing cloth over the design. Set your iron on a wool setting – NO STEAM. Temperature may be adjusted as needed. All irons are different. Place your iron on the pressing cloth on top of the design. Your iron will sit there a minimum of 30 – 45 seconds. Do not move your iron. Let it sit in place. This makes you nervous. BUT – the length of time and your temperature is what is melting the glue. Make sure your iron sits there long enough. If it sits there long enough and the glue isn’t getting melted, then the temperature of your iron will need to be adjusted. ***SHIPPING INFO***Standard Mail usually takes 3-7 business daysPriority Mail usually takes 3-4 business daysPlease note that USPS does not guarantee their shipping times and delays do happen from time to time.
