Speaking of panniers or bags.... I'm trying to overcome the logistics problems associated with my commute. Right now I'm only getting out for rides on weekends (and I skipped this last scorcher) because my class supplies are, well, difficult to pack. Annoying on the bus, probably dangerous on a bike: 14" 24" L-square and 24" hip curve used for pattern drafting.

Even without the rulers, my 80's vintage Traveler panniers don't quite fit on this bike as well as they did on my previous one. And they don't hold very much. I need to be able to haul a full complement of books and some sewing supplies along with a change of clothes and shoes and so far am coming up empty-handed since I don't want to buy anything without being able to look at it first.

Suggestions, ladies?
