I give street artist creds because I had expectations of how difficult using spray paint could be. I experimented on a card board box with a metallic blue and golden yellow paint. I found them on clearance at Michael’s, the craft store, for $4 each. I held the can a little to close to the box to get clean starlight lines, however the grooves on the cardboard box distorted how the paint laid. The blue was fine, however the yellow cap clogged. I started using the blue cap for both colors until that too clogged. Unfortunately I couldn’t clean the caps- I used a safety pin and soap to clean it, but no luck. I didn’t get to finish my name entirely the way I had hoped. My family and I are emptying out our garage and they gave me the approval to experiment with paint on the walls so I hope round 2 goes a lot smoother!
