Snazzy Quilted Diaper Wallet

I bought fabric a year ago and planned to make this little idea of mine into a reality for myself but I never got around to it. My sister in law liked my idea and wanted to try it but, I couldn't tell her how it had worked out since I never followed though on it. Long story short, I repented my neglect of the project and made one for her.

There is a pocket for wipes,one for diaps, one for a tube of whatever bum-goo you may need, and one that will fit a pair of baby nail clippers or a spare paci.

It rolls once,

twice,

and it's closed!

I haven't put a closure on it yet, I'm thinking a magnetic snap would be ideal. It needs to be strong enough to hold the wallet closed wile its jumbled around in a purse or diaper bag and also easy to open with one hand. The magnetic snap idea is the only one I've come up with that I think will really work.
In other news, I have fallen in love with my walking foot on these past two projects. I got it with my machine 5 years ago but I'd never even opened the box. I thought it was exclusively for quilting so, since I don't do much of that, I didn't bother.
What is it exactly that I like about it? I couldn't tell you. I can't figure out what it is that makes sewing with it easier than with out it, but I know there's something and that's good enough for me.
