In high school, I had a friend who said she was going to "fashion a satchel" out of things, so now I really like that word.
My neighbors got me this airbrushed shirt in Florida years ago, but I never wore except as pajamas because I think it's kind of creepy to wear clothing with my name on it. I cut off the collar and top seams, sewed up the bottom, and turned in the sleeves to make pockets. Now I have an overnight bag to keep useful things in my ghettomobile car.

None of the buttonholes are finished off and most of the edges are raw because a) I like raw edges and b) I am wicked lazy. The drawstring is actually a toga tie from when I was in Latin club. Someday when I am not poor I will replace it. I know that this is pretty rough and looks like something a homeless person would carry, but it's useful and was and took me less than an hour; sewing the buttons on took the longest. Most importantly, it was free to make! I just used things I had lying around, because I never throw anything away.
