Here is a series of pictures documenting my progress:
The finished pouch!
It was immediately gifted to my daughter who filled it with her "treasures." It was actually really simple to make, and I like the results immensely. (Plus my first zipper!) I don't like that turning the bag right side out ends up with a wrinkled outer pouch, though, and I decided to use an extra layer of fusible on the "real" pouch to make it a bit stiffer. Look for the post after the recipient gets it!
