Hit me with your best fundraising ideas

With a view to a xmas gift, our school just did a calendar fundraiser (just started selling them)- the kids paid $1 to get their 'art work' -drawing, painting, whatever on a theme - we did local landmarks- in a raffle/draw, then 12 were pulled and they went on Jan to Dec pages, an extra one for cover image and i think the others they put as a collage on the back - they ordered the minimum to be printed (maybe 100?) at a discount printer and are selling them for $20 (which i think is steep but each to their own)

Family movie night I missed but if there's a hall you have access to it can be pretty cheap to run - people buy tix but BYO chair or pillow or beanbag (and potential to sell popcorn etc for extra $)
