Use a chopstick and a soft cloth to clean hard to reach corners and crevices. The stick is small and easy to manipulate into tight spots. I especially like this for getting in between the fins in air vents.
If you need to paint polka dots, dip the end of a chop stick into craft paint, dab a little off and set it on your project. Keep the dowel level to the project, twist slightly and pick the dowel straight up.
You can also use a couple of chopsticks to set your project on to keep it off your work surface while you paint.
If you like essential oils, use a chopstick as a reed diffuser. Set it in a jar of oil and the oil will slowly saturate the chopstick and disperse the scent.
In the kitchen, use a chopstick to level off ingredients for baking.
It can also help to move slow moving ingredients through a funnel or seive.
Finally, if you want to teach someone to use chopsticks, try gluing the flat edge of some chopsticks to each side of a clip type clothespin.
This makes them easier to handle and manipulate for a beginner. Try it for yourself! I'm Mrs. Fixit and it's just that simple!
