I love this idea. Although I don't have little kids at home anymore encouraging little notes can be fun anywhere. Who wouldn't want one? I used to make notes like this to help my daughter with her SAT by giving her a word of the day and the meaning. Each day she got a little love note in her lunch.
I used Over the Rainbow set and some retired DSP with Whisper White and my all time favorite color of Tempting Turquoise!
