I made this from a juniors dress. I love the way it turned out.

I lined it with a yard sale sheet. The front pocket is held with a magnetic snap. I used the dress' existing pockets for the side bag pockets. The interior has two pockets. I salvaged the side zipper on the dress for the bag top.
It took a lot of creative cutting to get the correct size pieces for the bag out of the dress and I had
just enough.
So this bag cost only the $.25 for the snap and the pennies in cost of thread and electricity.
