Awww...hate it when things like that happen. I have really weak hands due to carpal tunnel and I am always dropping things. The other day doing dishes and cleaning the kitchen I dropped a dish, glass glass and a jar of olives one right after the other. What a mess I had!
I would suggest getting a couple of the magnetized pin holders. I knock mine off the sewing table with regular frequency and rarely do any of the pins fall off and scatter.
