I love it when people are passionate about things which I would never have noticed.
Like these insides of business envelopes - I had never given them even a moment's thought until I saw them today on Inchmark. Brooke even cuts them into little squares for making notes. But you can guarantee I won't ignore them in future. I probably won't give them quite the same attention that she does, but I love that somewhere out there, someone is getting excited about receiving bills. See this post for links to other images.
