Not using changing table

Anyone who is not using a changing table- what will you be storing the changing supplies in?

I kind of want a bag I can carry around the house to change whatever if need be but not 100% sure on that. I was thinking one of Thirty-one's double duty caddy things in maybe a gray cloud or darker design to avoid showing stains? I attached pictures of what I'm thinking. Will I have to constantly restock it though with diapers?

I'm definitely open to other ideas though.

What have you used and loved or hated?
