Ready to make your custom tees absolutely shine? Grab this Siser GLITTER Heat Transfer Vinyl sheet! It's a 12-inch by 20-inch sheet of pure sparkle, perfect for adding some serious bling to your apparel projects. This stuff is CPSIA certified, so it's safe for all ages—great for kids' clothes too! It's made from durable PU material with a pressure-sensitive backing that makes weeding even the tiniest letters and designs a breeze. You can layer it over other materials (just not over itself). Works great on 100% cotton, polyester, cotton blends, and even leather or Lycra (though it might crack if stretched too much). To apply, press at 320°F for 10-15 seconds with firm pressure, and peel hot. Care is easy: machine wash warm, tumble dry normal, no dry cleaning or bleach. Wait 24 hours before the first wash. Comes with a free hard-edge squeegee to help you get a perfect application. Time to sparkle!
