Firstly these were a series of drawings I did whilst away on our trip to the beach....
I used dense printing foam from Speedy School Supplies. This foam is harder than polystyrene foam and is easily scored using a pen.
The materials I needed, I didn't photograph the plate that I put the ink onto for rolling before adding it onto the printing plate.
I have only completed 6 prints in this series and this was the last one. Note how the image is the negative of the scoring.
Framed and ready to display!
