I have always givin to the staff at my childrens school. New teachers and old that I still see and talk to.
You can purchase multi scented lotion gift sets at Marshall's and TJ Maxx and break them up to wrap them in tule or decrorative tissue paper with ribbon and a gift card for each person made on your computer using business card stock, and for the male teachers I get nice sock packs (nautica, ect...) for 5.99-7.99 to 3-4 pack. Sometimes I have even baked cookies, cupcakes, made chocolate candy bags or supplied lunch for the office staff since I know them all (3 years).
Lunch was spaghetti/gralic bread, chilli cheese dip with totilla chips, or sandwich rolls. Cost usually around $15-$20. Each year I try to give something. I think this year I will get a cake from Sams Club or make a fruit tray, enough for most/all of the office/teacher staff as they come and go or while on lunch break. Send it in with a decorated touch.
I've given nice christmas ornaments too.
All will be grateful.
