Just finished a design for the local High School science club. If you couldn't guess their theme is lightning this year.
Planning to print all white on a dark blue shirt. Going to do 2-3 hits of opaque white and dual screens for the low-lights and high-lights of the clouds. High-lights will also get a double hit of the white to achieve the depth i'm looking for. I'll upload a pic as soon as I get them printed.
Let me know what you think or if anyone has any expertise in the matter feel free to throw some advice my way.
