First of all I have to send a shout out to one of my college friends, Adrianne, who is the author of Cog Works. Not only did she provide you with FREE printables for parent volunteer gifts, but some of these could even be adapted to become a teacher thank you gift. Thanks Adrianne for sharing!

Make a tag that reads: "My teacher is AWesome!" and attach to the top of an A&W 6 pack or liter bottle.

"You're the apple of my eye" and other catchy sayings to attach to (non-pop)drinks from Darling Doodles. Soda pop tags can also be found HERE. Oh and can I just say, she has the greatest ideas for gift baskets for all occasions!?! I will definitely be visiting her site the next time I am in need of giving a gift!!
Even though this next one isn't pop, it's close enough. I wish I knew where this idea came from, but I found it on Pinterest without a link back to the source. :( Let me know if you know where to find this idea so I can give credit. Anyway, judging from the picture, I would say to fill a cello bag with lemon flavored items such as Minute Maid pink lemonade, Lemon Heads, lemon drops, crystal lite packets, lemonade flavored bubble gum, etc. and attach a tag saying: "When life hands you LEMONS, make lemonade!"
