The gem I found while browsing our tumblr followers this week is the blog of Gavin Ashworth, a student in New Zealand. His messy collaged doodles are made on found paper (some sheets look like school papers), sometimes incorporating unexpected materials like wood and melted plastic. It's a dirty, damaged mishmash that looks disgusting and awesome at the same time.
If you're addicted to tumbling as well as doodling, follow Doodlers Anonymous on Tumblr for even more daily inspiration. You might even see yourself on there!
