I got the pattern from mmmcrafts (for free!. I used some great fabric that I won in a giveaway from Jessica at Quilty Habit.
One of the things that I like about this bag, besides being really easy to make, is that is has a distinct bottom.
I added an extra pocket to the inside, since I figure that too many pockets are better than not enough. I'll also admit...the inside wasn't finished by the time I wanted to use the bag. So I used it without the inside in place and the extra strap length stuffed in the bag. I figure that it gave me a chance to check out the strap length before committing to it.
