Thank your volunteers for their help during the school year. Give them a certificate at the end of the year, end of the semester, at a "thank you" luncheon, or at any time! These watercolor grape-themed "thank you" certificates will really show them they are appreciated! There are four versions in the set so they can be given to volunteers by individual teachers or principals or by a class or school. Add text by hand or on the computer (directions included).
