I like to give some sweets and a "thing" of some sort for party bags, rather than a lot of bits and pieces. So far, ds has had helium filled balloons, torches and magic tricks. And ideas for this year? I need 20, so not too expensive. And I thought of books, but I have realized that he has invited a HUGE range of reading ability, so that would be tricky. Would magnets be a good idea?
