For those of you who use these can you tell me if they will be stable enough to hold up a 14-12-8 inch round fondant covered cake?

Joanne

You just need to use enough. the 12' should have 5-6 dowels.

Yes, use 8 in the 14 and 6 in the 12 inch.
I have used bubble tea straws to successfully support 2 tiers above of fondant covered fruitcake.

Thank you for the replies.

Joanne
