I set out to make a bag for my sewing supplies. I found this nice picture tutorial: http://www.make-baby-stuff.com/diaper-bag-pattern.html , added my own creativity and came out with a pretty cute bag. The pockets feature velcro, zipper and button closures and it will easily hold all of my sewing supplies or everything you need for an outing with the kiddos.
I might just use it as a diaper bag so I have a reason to take it out of the house. ;)
