Easy to do and cheap, but i was not thrilled with the star shape...
120 crayons - $6.97 (Walmart)
Star shape bowl - $1.00 (Dollar Tree)
Hot glue gun - $1.00 (Dollar Tree)
Bag of glue sticks - $1.00 (Dollar Tree)
Each star i used 60 crayons and maybe 2-3 glue sticks
i put in the center a $1.00 sunflower (Dollar Tree) that moves with sunlight
I am going to look for something round, so i will update!
