Day 1: With no plan or particular idea in mind, I set up a canvas and just started spraying. Whoa, were these cans difficult to control! And blending? Not a chance. :(
Day 2: I bought some skinny caps and Montana Black translucent colors ("Magic Black" & "Magic White") to see if I could get more control of my lines, and also create some shading. Better!
Much respect to all the awesome street artists out there - now I can see how much time and practice goes into what you do, and I look forward to getting my spray paint skills up to par with my traditional painting skills!
