I used to find lots of pins under my chair at the sewing machine. I am pretty careful about using a pin cushion as I like to go barefoot in the sewing room. One day, I caught my tortiouseshell cat,Rags, picking them out of my pin cushion and dropping them on the floor! She is 18 now and not as mischievous as she used to be. Must be the 4 dogs that follow her around! They SNITCH!
