One of my regular tattoo shop clients asked me ot come up with a new gift certificate for them. I tried to stick to a clean and classy look that had a bit of "Wow, I just got a gift certificate from Lefty's, this thing is awesome!"

 

I also wanted to make it something that would be hard to lose/easy to spot in a pile of stuff. Other than that, my usual less is better approach. I built the entire project in AI, creating the outer border by hand.
