HI! i can't seem to get enough of collaborations. Is their some other place you can find challenges and artinspiration that you know? I would really apprieciate it, even though i understand it may not be relevant to ask about it here! /Love Claire
First thing that comes to mind is The Art of Getting Started, where founder Lee Crutchley posts creative assignments every Monday. You submit your “homework” which later gets posted for all to see. Also, Doodlers Anonymous sometimes has doodling challenges and contests. Definitely check them out!
