So, I was having a problem storing my glass Pyrex baking pans.  We have just stacked them up and when I want my biggest pan, I had to unstack the who pile.  That was just an accident waiting to happen.  So I pondered how I could store them neatly, easily, and safely.  I came up with this.  Vinyl covered shelf dividers.  I use them in my closet to keep my purses and sweaters orderly.  Why not my pans.  So I slipped them on the shelf and started loading in my pans.  It works wonderfully.  So easy to install, they really just slip on, and adjusting the width is just as simple.  Love it, and no more complaining from other family members when they are fetching a pan or putting it back after clean-up.  Everyone's happy!
