Ran across this on another forum.......grand idea.
It was from a lady named Leigh......
"Looking for fantastic cheap or free display shelves for your rubber
stamps? Many of you will have an old baby's crib in your attic or
garage. They are also sold cheaply at garages sales, salvation army
stores etc. Look for one with wooden slats for the sides. Remove the
hardware from the entire side piece, turn the side of the crib on
it's end, and viola! Beautiful stamp shelves! The slats make the
perfect depth shelf to display your wood mounted stamps."
