re: Humidity...

I personally find that modeling chocolate doesn’t do very well in the heat, the kind I have made gets really greasy and it doesn’t set to be hard. Mayen (from Way beyond cakes by Mayen) has posted a picture on facebook showing how she sets up her flowers etc to dry using a dehumidifier. She is one of the many cake geniuses out there so it must work. Good luck, it is humid here as well (Nova Scotia) and I am fighting as long as I can to keep using my swiss meringue buttercream
