Sister Bunneefied was examining her religious vestments in the orphanage where she worked. The items below were hanging in her closet:
Hanger 3: soiled-beyond-redemption cape
Wall Hook: worn and tattered tunic that was beyond salvation
Doorknob: even the devil wouldn't be caught dead in that frayed and seam-ripped wimple
Hangers 4, 14, 26: veils and scapulars full of holes and tears
She quietly and methodically gathered each of them up and put them in the orphanage donation box for the poor.
What was she doing and ... what's the rebus?
