I went on a sketching scavenger hunt around Manhattan today. Something I plan to do more of.
You should try it!
Here's how: List a bunch of things to collect. Cut them into strips of paper. Put them in a hat. Pick out 10 or so. Then GO!
Some examples of mine:
1. Something burned
2. Something over
3. Something under
4. Something that won't shut up
5. Something trying to be something else
Or whatever you think of. It's fun to hunt them down.
