How To Use - Keep the back clean before ironing and adjust the iron to a suitable temperature. Put the cloth in the right position (do not tear off the glue), iron it several times, usually about 10 seconds. To prevent scalding, place a thin cotton cloth (not a faded cloth), check that the edges are ironed, edges can be ironed a few more times. The best way is to use a needle thread to sew a few stitches on the edge of the cloth after it is hot. This is more firm. Size - Oval: 11*14.3cm; Rectangle: 9.5*12.5cm
