Turn the steam OFF. Place the shirt on a firm, flat surface. If necesssary, iron the shirt before applying rhinestones.<br> Insert a piece of paper between the front and back of the shirt so the glue will not seep to the back side.<br> Inspect the rhinestone design. On a hard surface, press fingernails over the plastic to nudge offset stones back into position. If desired, trim with scissors.<br> Peel the white paper backing off the plastic transfer sheet. Place the transfer sticky side down on the fabric. It may be gently removed and re-positioned at this point. Inspect the stone layout once more before ironing.<br> Iron the transfer with firm, even pressure. Do not wiggle the iron. Press and hold the iron onto all areas of the transfer for about 10-15 seconds, depending on the size of the stones. Larger stones take more time; metal studs take less time. Make sure that all stones are heated and have pressure applied.The stones under the irons vent holes will not receive pressure, so re-position the iron once or twice to compensate.<br> After the plastic is completely removed, briefly press the iron to the stones to reset any that may have loosened.<br> The garment can be machine washed inside-out on a gentle, cold cycle. Lay flat or hang to dry.
