End of the Year Volunteer Gifts

Since I looped with my class this year, I couldn't do my usual painted flower vase, Tervis Tumblers or decorative beach bag gift for my awesome parent volunteers. I also ran into the issue of having a MALE volunteer this year. What in the world would I get the kids to make for them? One day I was searching the aisles at A.C. Moore and stumbled upon these cute wooden bird feeders. We spray painted them green and then turned each child's thumb print into a birdie. All I need is a corny saying…Thanks for FEEDING our knowledge all year?!?!

What sort of things to do you make for your parent volunteers for end of the year gifts?
