I am so NOT a designer, but the idea of designing and printing your own fabric has me a little obsessed lately.

You can upload any jpg or tiff or other photo file and create your own custom fabric. Some of the examples from other users are AMAZING!
Here are a few ideas I've come up with just working with different fonts and my very rudimentary level of photoshop skills.
