the top one is from karen. i paired it with one that i addressed to myself, for a client, who happened to have me on the guest list. i paired this odd couple because my blog is about inspiring people to pic up a pen or marker and make envelope art and karen is uber-educated in calligraphy and i don't think you can just pick up her skill by looking at it.
on the other hand, the stuff i do is uber-easy, which means you could probably pick it up just by looking at it. it's just regular penmanship with some variety in slant and some little secret curves here and there.
