Context: After I taped all the poster boards down , I gathered markers , rulers , crayons and stickers for the kids to use to " enhance " t their poster boards , creating their own a little backdrop for their Lego creations . One drew Outer Space , one drew an Ocean , and several drew Roads and Trails ... The amazing thing about this party is how well it worked . For the first hour the kids were so quiet and in to their building they hardly made a peep . We adults almost forgot that there was a birthday party going on at all ... I think the age of the kids helped - no fighter over toys etc . that might happen with kids Miles age .
