DS is having a birthday party soon. I'd like to give the kids a little something to take away with their cake but, as a parent, I cringe when I see the party bags full of plastic crap come out. 90% of it ends up in the bin within half an hour of getting home. It's a waste of money and I don't really want to contribute to landfill.
Any ideas of cheap but non-plastic-crap stuff I could put in them instead? I can only really think of books but suspect that'll end up quite expensive for 30 kids and might come off as a bit wanky. Help!
