Ok, so here's the tutorial, it's super quick and CHEAP...
(the images are not very good, but you get the idea)
Sooo... you need:
-some light material ( i think you can use just about any type of material but the image will always turn out slightly different)
-genuine turpentine (I tried substitutes, they don't work)
-duck tape or something to fix the image
-a spoon and a brush
and of course an image, b&w or colour, it needs to be printed on a laser jet printer or simply photocopied
-tape the image upside down onto your material
and brush turpentine onto the image, do this with Windows open, as the fumes are very strong
now start rubbing the image onto the material, do this at first only with the round side and then the edge, being careful not to tear the paper
Repeat this a couple of times, putting more turpentine on and rubbing all over the image.
Now peel off one side and check if the image has transferred strongly enough, otherwise keep going.
You can also layer a number of images
I found the image starts to fade a little bit in the washing machine, but I quite like that...
