I discovered the block was missing after the garbage was picked up...
Now I check the waste can before tossing the contents into the household waste. Lesson learned.
The garbage can was my thought, too, only because I've caught fabric pieces falling into mine when the piece moving through the sewing machine drags it. I now try to remember to move the can farther into the room so anything which falls or rolls off the desk will land between it and the desk, instead of inside the can.
