I am always looking for new storage solutions to reduce some of our clutter, mainly craft-related things or toys with small pieces. One thing that seems to be economical, healthy, and useful are those plastic clamshell containers from the Earthbound Farms pre-washed greens.
Economical- we're already buying the lettuce (can't grow our own because it's too shady)
Healthy- encourages salad consumption and is a way to "reuse"
Useful- they are clear so you can see what's in them, they are easy for a kid to open, and they stack for even more storage
Got this idea from my mom- thanks!
