This is a good idea. At last year's reunion in the park, we recycled all of our plastic bottles. Also, instead of purchasing an expensive vinyl sign from a professional printer, I went to a home improvement store and bought heavy duty canvas cloth for less than $10. I also purchased fabric paint and stencils from the craft store. I got the teens and tweens together gave them the supplies and let them make the sign. The sign came out great!!! Some of the family thought it was made by a professional! We will use the same sign for this year's reunion.
