Congratulations on your brilliance! Now you can file! Thin and smart, a killer combination ...
I knew if I just let it alone, I would have the answer. My brain works like that, sometimes. Now, if my files over-run the two drawers, I can make a third (drawer) by assembling another frame set and setting it on top of the file cabinet. (Though I have no clue what I will do with the file sorter that’s on there, now.)
I went to Walmart to find some knee-highs and some panty hose, and when I got back, I realized I didn’t feel like going to church today. :o[
