While surfing one night I came across this technique of cutting away the top surface of a piece of corrugated cardboard exposing the inner ribs to form a design. This was my first attempt. Later I will add some tangling to this piece filling in the smooth spaces.
These are the tools I used...The serrated wheel for marking the lines, X Acto knife for slicing through the top layer of paper, skewer (not shown) for sliding through the grooves and lifting the paper and removing, tweezers for picking out hard to reach spaces and Staedler pigment 0.5 & 0.8 tips for doing the zentangling.
I have so many ideas of ways to use this technique!
