I've had problems in the past with MMF tearing and ripping on large cakes. I need to cover a 14" with MMF. Can you cover one that large with MMF and is there a way to make it pliable and not rip and tear? THANK YOU!
When I have that problem I have found it is usually because I have rolled the mm fondant too thin. I roll it about the thickness of a cake board, now.
I've covered a 16" with MMF. Add a couple of teaspoons of glycerine, that should help.
