I need to make a birthday cake for my grandson for next Sat. and wanted to know how early I can cover the cake board with RKT and Fondant? I wanted to get a head start since I may be attempting more than I can accomplish! The idea is to cover the board in RKT so that I can make it look like ocean waves and then cover with blue fondant. Also, how far in advance can I make the fondant decorations (monkeys and palm trees)? Any advice would be GREATLY APPRECIATED!!

I have made my creations and covered my boards up to a week in advance. My fondant recipe says that fondant is good for a week to 2 weeks out of the fridge and 1 month in the fridge. I have never had any problems doing them a week early.

The longer that board dries, the easier is for you to work on it

I would agree, a week is totally fine. I like the board to get really hard to I don't put a finger print in it!

Plus if you do it early and you mess up you can do it again with out the time crunch best of luck.

im pretty sure you can do it a couple of days in advance
