This time a bigger one (Din C5) for more space...! Okay, to be honest: I had the skull printed and cut out with a paper knife and I had tried to sort a little bit my stuff so per chance this kind of envelope was catching my eye ^^
I cut out some speech bubbles: The upper one for the stamp and the lower one for the adress label. I also added some "thoughts" for the shipping adress.
Then just a little bit of artistic water colour... and everything was outlined with a black pen. Fast, easy and I think it is somewhat cute ;)
