I'm making my first CC Bouquet today & didn't do too bad on the flower, let them set for 30 minutes before attaching to toothpicks in my base, so far, so good. Go away, come back hour later & several "flowers" are laying on the counter! Cupcke is still attached to base, just no flower. Tried to keep CC as upright as possible. What am I doing wrong? Icing seems to be right consistency. HELP!
