If you want a simple, cheap way to keep a grocery or to-do list in your kitchen, or wherever else, try a roll of the ever useful butcher paper. It's a pretty simple idea, but I do like the thought of having a list that's easy for everyone to find and write on, but that isn't on the fridge or sitting on the counter somewhere getting in the way. And it serves as it's own reminder. When the list gets long enough that it hits the countertop or floor, it's time to take care of some things. You can use butcher or kraft paper or, as At Home In Love suggest, painter's masking paper from your local hardware store. It's cheaper, the paper's a bit thinner and the rolls are a good size.
