I am making my daughter's graduation cake and I plan to make the cap and stack of books out of RKT and covering with fondant. My question is how far in advance can I do this and make sure the fondant don't turn icky? I work full time so I am preparing what I can the weekends coming up to the party.

I have made some of my additional pieces to a big project and it's not due until 2 weeks from today. I bought thr RKT from the store (they have the preservatives so it wont go bad like made from scratch with butter) and I used my "glue icing" 2 cups conf. sugar, 1 tbsp shortening, 3 tbsp light corn syrup, small amts of water until thin consistency. Covered with fondant. It will dry a bit but just be sure you've decorated it and it will be fine! I check mine daily and even have pieces I made and didnt use for another project and their still fine. Just store pieces out of direct light and you'll be good to go! Congrats to your daughter graduating!!!!

Thank you so much YellowBrickRd. That makes me happy as I am so excited to get things rolling. This will be my first.
