I take an empty tissue box and store my plastic grocery bags in there.
Another thing I have done is taken an empty wipes container and took the lid off and store my plastic wear lids in them on the shelf. It keeps all the lids in one place and neat.
I have taken an old plastic similac container and I use it to store loose things in my pantry like taco seasoning, loose packs of oatmeal, kool-aid packs and lipton onion soup mix.
I use an empty wipe container to store my kids loose puzzle pieces. Right now they are not into doing puzzles but they like to put the pieces in and out of the wipe box. And they can even work on putting the things in the wipe box through the little hole and that helps their fine motor skills too.
