Could you get parents to have their kids write letters and combine those with a picture of the kid? Its pretty easy to get stuff like that bound into a book, especially if its all scanned and sent that way.

DC's homeroom teacher is leaving the school at the end of this year. We loved her and would like to make some fond memories for her. Need ideas for gift and/or activities. Either individual (from DC) or a group gift from the class (though I'm not the room parent). TIA!
