I went to SSWC 07 and there was a lady there who was American but living in Germany. She made custom messenger bags out of tarp and I've been promising to buy one for years, but I've finally got a job where I can ride to work every day.
I think the "company" (it wasn't so much a company as her making bags in her spare time) name began with a "T" and I'm sure someone on here had bought one.
It's a long shot I know, but has anyone got any idea what the name of the company was? They have a flickr page but beyond that I've no idea!
