for this you will need
a4 piece of paper
printer, mine is an inkjet printer
something to rub over back of image
first lay out the grease proof paper (make sure the shiny side is on the opposite side, and get the spray glue and spray it to the back of the A4 piece of paper and stick together.
then you need to cut around the grease proof paper so that it is the same size as the piece of the paper. then its ready to print on.
i chose to put the image on to this with wooden tray.
i found this image on graphics fairy.
put the paper intothe printer so that it prints on to the grease proof paper. make sure to mirror the image on the computer before printing
then place the paper ink down on the tray and rub the back to make sure the image is transfered. i used a bank card.
if the image has parts missing then, you can go other it with pen or paint.
