I bought some tenugui fabric while in DC for work. It's Japanese cotton towel fabric. More about it here.
Before I left, I put together a new totebag. It's quite similar to its predecessor but I made a few tweaks, including adding piping. I now think piping is awesome. Easy to add, and makes a more professional bag. It makes it almost look not homemade.
The lining is vintage daisy fabric. Special padded pocket to perfectly fit my netbook.
