A GREEN Party! When my son was turning 3, he was OBSESSED with anything the color green.  When we asked him what sort of party he wanted, he said GREEN! We traced his hand on Green construction paper - so when you opened it, it looked like a butterfly - and wrote the invitation inside. Everyone was REQUIRED to wear green!  We ordered the cake decorated completely Green! And served it with Mint Chocolate Chip icecream. The plates, napkins, streamers, ballooons, silverware - all were green! The treat bags were green and were only filled with green goodies!   My son's hair is blonde and we sprayed it green too! After that party, other children we know wanted "color" parties!
