Speaking as an Elementary School teacher, I really appreciate things I can use rather than things that sit on a shelf and gather dust. Homemade mixes ( cookie, bath, etc.), gift certificates to restaurants or teacher stores, items for the classroom (stickers, rubber stamps, children's games, etc.) are always appreciated. I too had cabinets full of mugs, trinket boxes and statues until I was forced to get rid of them for needed space. Unless you know the teacher collects a certain type of item, please don't buy it. The thought is nice, but storage gets to be a real problem after a couple of years. Great ideas in this thread!
