We bought a smaller camera to take with us on trips (our main camera is kinda big and clunky) and I whipped up a little camera bag for it.
I put a layer of quilt batting in it, and a little pocket on the inside for an extra memory card.
I threw it together so fast, I forgot to think about a closure until I almost had it all together. So I just used a couple of buttons and a length of (very cute) ribbon and did it like an old string-tie envelope.
I think the camera is happy in it.
