I don't fold and put in the Ziploc bags.. I just shove them in
I am thinking after this thread though that I might just have them put them in a dollar tree bin and place them on the shelf- again I wouldn't fold them just have the kids put them in. My shelf is high on the wall so they wouldn't be accessible by the kids because if they can get to blankets they do and we wouldn't want them contaminated with their sleeping blankets only our play ones.
