Designer Channel Bag

I made this cake for my kid sis birthday and as you can see it was sweating,though it kinda worked to my advantage giving the bag a patent leather look (huh).Bottom line i need to stop these cake from sweating..thing is ,I just moved into a new place and i guess the house is not fondant friendly. ive read about humidity and i plan to put some things in place to counter this effects.fingers crossed.

well wish me luck!
