I am also in love with Hershey Kiss stickers! I found the stickers and the matching tags here (you just send her your email and she immediately sends the files to your inbox). I bought four $1 store canisters and filled them with Hershey Kisses with the school-themed stickers on the bottom. Added a tag and some ribbon and done!
Then after dinner tonight, I had the kids help me make these darling owl gift bags to put our Kiss jars in. The kids did all the cutting, punched out all the circles, and wrote "Thank you for making me wiser" at the bottom of the paper bags.
