I love to walk about the yard and pick up sticks and bring them into the studio!
Shown here is my .03 lead mechanical pencil. I once used a .05 lead but found the lead to be too thick. The ".03" is just right!
I also found that drawing on cold press watercolor, while it has texture, is perfect for laying down graphite. Much easier than hot press and many drawing papers for a professional artist grade project.
Here I am working on Fluid 100 cold press paper on a block. The blocks are easy to store and ready when you are to start a project.
