The challenge this time around is to use something from your art stash that you've never used before. Whatever that means to you or however it inspires you. The prompt is simply meant to get you started. The level of challenge you aim for is entirely internal and up to you.
For me the something new is a white charcoal pencil. LOVE the look against kraft paper (I love the look of anything against kraft paper!!)
