Portfolio Case
 

I'm only able to commute two out of four days (days I don't have drawing classes) to school because of my portfolio case. Its an 18x24 flat nylon bag that carries my drawing pads and other art supplies. I was wondering if you guys have any ideas of a way to attach this case to my bike. I realize that it will catch wind like a kite, but I'm willing to give it a try. I ride a Fuji Del Rey fixed gear with a rear rack. My commute is 24 miles round trip and I go through Downtown Detroit.

Thanks for any suggestions.

You could attach pannier hardware to it. Something like this....

You would have to do it at one end and let the other just stick out.
