Design Your Own Limitations

Use permanent ink to sketch your next idea. No erasing. No restarting. Whatever ink hits the page stays there. Do it a few times with different types of pens or markers and see how the design evolves. Don't get caught up in it being “perfect.”

Try these:

Use only one font in your design. 
Use only two colors. 
Don’t use the Undo command. 
Don’t design with layers.

You'll force yourself to be creative where you might not have normally been simply by creating your own limitations.
