Had a tooth-shaped fridge magnet around for ages. It said "Smile! Keep your bite bright." Obviously, it came from a dentist.... and so had his contact details on it. Not much use when you have moved houses, and countries! :)
So I decided on a makeover. At least the message on it remained relevant even otherwise; a smile never hurt, did it! So I added some artwork, and gave it a new look.
The kids loved it, identifying each of the food items I'd drawn. And the fridge looked a tad brighter for the splash of colour on the white magnet.
p.s. - Sorry about the picture quality; I know they are hopelessly hazy but I used my cellphone camera as the digital ran out of battery. Lazy ol' me! :)
