I just got my first order of supplies. I got a Quart of Calhoun 1207 plastic. Light Watermellon, Green Pumkin, and june bug colors. Red and Black glitter. 8oz of calhoun softener. 1 quart of ultra fiine salt. Can someone give me some color ideas that I can make with this combination of supplies. I am wanting to make some green pumpkin worms and watermellon red worms. When do you add color to the plastic and when do you add glitter and salt?
