When you drop something tiny on the floor/carpet, like a pin, screw or earring. Take a flashlight and put it level with the floor for the light to pick up the shine of the lost item.
Another idea to find something small that you've dropped and can't see. Put a piece of net, cheese cloth or old pantyhose over the end of your vacuum cleaner hose, secure with a rubber band. The suction will bring it to the hose but the material will keep it from getting into the machine.
I sew alot and I am always dropping pins and needles..I use a magnet attatched to a string and just run it over the floor and when the magnet is full you just pull up the string...alot easier than getting on your knees. By Jacensgramma
