We had eight little friends from daycare attend with their parents, so it was a good group. The weather was amazing, high 50's so we did most of the party in our yard.
Here is what we did:
As they arrived the kids decorated a Boo Boo paper bow tie. When they finished I taped a mini paper clamp to the back so they could clip it to their shirt. The parents ended up wearing most of the bow ties.
