I bought the felt item from Daiso and decided to make a costume for son, it's a spider costume, If you visit www.mymomsbest.us you'll see the picture.
For myself the black spider costume, I used the black fabric that I bought. It's diy costumes as purchase or rental are expensive.
It's fun to join the costume walk/dance though we didn't win but we are happy to be part of it.
Son is happy that day, apart collection of goodie bag there's certificate given and a medal as souvenior.
