I think I would cry if a student gave me this. Green is for the inspiration you give me each day. Blue is for your patience in showing me the way. Orange is for your warmth and caring style. Yellow is for the way you always make me smile. Red is for my life that you have touched this year. You place knowledge in my hands, that melt into my heart and live forever! You're a "Magnificent" & "Marvelous" Teacher! Thank you for being my M!
Paint samples are really cheap (cheaper at Lowes than Walmart). Grab a blank canvas (also cheap), use painters tape to make a design, and buy a size appropriate wooden letter, or smaller letters to make a word, and paint those, too. Bam. Awesome art.
