Everybody loves a free gift! The feedback we have received is that how many to bring depends on how many kids can participate in your activity as well as how popular the activity is. Can you do 300 interactions per hour or only 3? Most groups find that 2000-3000 items are plenty. There are however, some restrictions on what you can bring-- please do not give-away stickers, food (yes, candy and gum counts as food) and do not give away pens, markers, or sharpened pencils.
