Antique Hat pin, use it to hold that last micro inch as it goes under the needle. Painters tape to lay out grid lines to keep my quilting lines straight, Pin cushion I made using .0000 steal wool in it to help keep needles and pins sharp. Rubber shelf liner under my foot peddle, keeps it from walking around under my machine. Small magnet on a extending arm (found at auto store) for picking up droped metal things, pins, thimble, scissors, its really great when something rolls under something I cann't move.
