I spent last night trying to come up with a suitable banner for my Etsy shop. My user name is Moonflygirl, which I chose long before I ever intended to sell anything - but you can't change it - so I have to make the most of it. I used photo of the moon surface as inspiration, and added my own little bits and pieces - some bunnies, flowers, saturn, a rocket... you know, stuff you find on the moon!
Here is the result, I'm quite pleased with it, but this is version #3!
I used the same illustration to design the Avatar, which seems to be quite important (but so tiny!)
