I have been trying to figure out a good way to keep my pan lids from falling out of the cupboard but still have them easily accessible. I found this dish rack for $3 at the thrift store. It could also be used to hold storage container lids. I can just slide it out when I need a lid, they aren't falling out or getting shoved way in the back of the cupboard anymore.
Another organizing idea to store pan lids (from my sister) is to use a file rack. You can find them at the thrift store or at a department or office supply store for under $5.00. More Kitchen Organizing tips
