I bought this fabric at JoAnns on sale and it ended up being right around $4/yard! My favorite is the polka-dot fabric of the lining.
I can't begin to tell you how much I love the outer pockets on the diaper bag. They are large and easy to access.
There are 3 (hidden) pockets on the outside and 3 on the inside (on the other side of the bag). For some reason it has been so much easier for me to remember what pocket things are in with this layout. My husband definitely appreciates that!
