As this image shows, wax can be removed from the card surface using the
heated iron to remelt it, whereas on regular absorbent paper the wax will saturate &
impregnate the fabric of the paper, making it impossible to remove once applied or at any later
* Absorbent surfaces can be great to work on, but for initial iron techniques it is best to use this card or similar.
