I'm doing a three tier topsy turvy and want to know If it would be safe to stack the two bottom tiers tonight.. Basicly 24hours before I deliver.. the cake is fondant 14 and 10 in. pretty heavy what do you think?

I stack all my cakes the night before. Of course i haven't done a large topsy turvy cake. But if you are using the method where you cut a hole in the top of the cake so that the next cake can fit in it, i would think you wouldn't have a problem. Just make sure to properly dowel.

As long as you are supporting the tiers well I do not think you will have a problem stacking in advance.

I always stack my cakes the day before. Even if it's 6 tiers, it gets stacked, decorated and delivered that way. As the others said, so long as you have the proper support, it should be fine.

thank you so much! I use bubble tea straws for support if thats good enough support I think I am just going to stack the bottom two and finish at the site (too nervous to do it all ) but now at least It will be easier to do my bow when the cakes are already stacked..

Absolutely not a problem... al my cakes are stacked at LEAST a day (if not two) before, since I don't decorate them until they are stacked!
