This by far is the coolest pen pal program I have signed up for :). I found the swap at the Natalie Blair Blog. I was paired up with Melanie writer of Now a Queen blog.
The mug I got for Melanie was a bright burnt orange mug at the store it just called to me. Here is her post about the mug (mug post). Once again this was a fun pen pal thing to do and I have already signed up to do one again.
