I used a variety of charcoal, pastels and pencils in black, white to make marks, along with more white gesso and a spray bottle with a rag as erasing tools.
I made random mark making then defined shapes that "spoke" to me and "erased" the areas that I found distracting with white gesso.
My ah-ha moment came when I saw a mid century upholstered chair in the lower right area. I do love mid century chairs! I gave it a home, a lamp and a friend.
This experiment was really freeing because I never, ever draw and have long considered it something I just couldn't do. (Like driving in NYC or surfing). The selection of drawing tools were left here by my ex 15 years ago, and being a packrat I held on to them and even remembered where I put them.
