Sometimes just seeing things in writing can make a big difference. If you're tired of nagging, "Turn off the light in the other room," Ecominders are a simple way to leave little reminders for your family.
The Ecominders are clear stickers and you can get them in a set for your home (shown above) or for kids and schools. They're also removable and reusable so you can pretty much stick them anywhere.
