Feel free to express yourself here if you have an idea for a stamp. I'll try my best to satisfy as many suggestions as possible. You can suggest anything -except what goes against dA's policy- cosmically random stamps, supporting stamps for the deviants you appreciate the most,events, contests, In Real Life manifestations etc.
You sure will be credited in the description for the idea, the stamp is yours after all
Let the brainstorming begin!
tl;dr: comment down suggesting a stamp.
