For an end of year teacher gift, I found this cute M&M poem online. I don't remember exactly where I got it from, but it is really easy to find if you search for it. I bought some glass jars from Ikea and filled them with M&M's. Each jar took about 2 regular size packages of M&M's.
Then using my digital scrapbooking program I made a 5x7 with the poem printed four different times with the teacher's name on each card and each of my kid's names. Doing it as a 5x7 I was able to have each card be approximately wallet size and I only had to pay about 40 cents to have it printed. The wallet size seemed to work out well with the size of the jars.
I hope that the teachers like this gift. We appreciate everything they do for our kids!
