Stole this idea from another pinterest post....Hung balloons upside down using streamers.... Gave me a great pic of the birthday boy waiting for his party guests!! 1st-birthday-yo-gabba-gabba-style by candy
Fun rainy day activity for the kids (or Lego Ninjago Birthday party idea). Uses party streamers taped at different angles between walls, ceiling and floor. Lots of fun and a big success with ten 7-8 yr old boys.
