People have been doing this for thousands of years. Making texture into images and memories into art, something they did before "photographs"
Here Bekah, R.J and Grandma are rubbing dinosaur prints that are in the cement.
- Locate the object or surface you would want to rub.
- Lay a piece of paper over the object, then tape it in place
- White paper is fine, but you can use vellum, that way you can see whats underneath.
- Peel the wrapper from the crayon and rub its side all over the paper. The crayon will catch on whatever is raised, creating a clear image of the surface.
