Draw onto paper first, thus enabling any mistakes to be rectified or images redrawn before applying to the fabric. Lay the finished artwork face down onto the fabric and then rub with a hot iron to transfer the image. Full instructions on the pack. Add extra fun by writing backwards. The crayons do not truly reflect the finished colours as the heat from the iron intensifies the colour. Can be used directly on fabric. Wash new fabric first. Pack contains one each of cerise, yellow, orange, red, purple, blue, green, black, brown, dark green.
