Teisha...how exciting! I've never competed so I don't have any first-hand tips but here's an article Earlene wrote...
And also one by Diane on covering your cake boards with hints for show-work entries.
I'm not sure if this is the same Earlene article that Lisa linked you to, but Earlene has a big section on her website about cake competition and what the judges look for.
Would you use a buttercream or fondant for a cake competition display. I am concerned about the buttercream cracking.
I've watched a lot of the competitions on TV. Seems like 99% of the cakes that have to be displayed that way are done in fondant. I would think a fondant covered cake would hold-up better than a BC one. I don't know what a BC cake would look like after being left out, uncovered for a week. I think it would dry-up, maybe crack.
Good Luck Teisha!!
How exciting for you! You will be posting what you enter, or can you do that once the show is over? And is there a theme which you have to follow, or just make what ever you would like to? I'd be a nervous wreck but it would be fun!!! Wishing you the best!
Have fun with your cake and enjoy!
Have fun and good luck.
