very easy to use: just follow the instructions ... Carefully follow the ironing on a flat and hard surface !!! (Do not do on an ironing board because otherwise the transfer is small "bubbles" with carpet ironing and the result is not terrible !!! board on a wooden board with a tea towel underneath (or very fine linen). Otherwise, the result is impeccable, works with all conceivable grounds. Great to customize your own t-shirts
