After some searching I managed to find my little booklet. I got out my pens and started drawing. I had a hard time drawing my keys. My dog kept on interrupting me because she didn't like that I had more attention for my silly pen and some paper than for her. She tried chewing on my pen while I drew and I finally managed to distract her long enough with some treats.
I've had this backpack for I while, but had never drawn it before. During a cleaning-spree I found little Kenny-the-keychain and hung him on my backpack. He frequently suffers attack from my dog and other dogs, that love to check him out, leaving me screaming "OH MY GOD, DON'T KILL KENNY!!". I don't scream too often though.
Very happy with how the backpack turned out.
