I am wondering how far in advance I can make fondant sculptures like people or amimals? And do they dry out, if they do how would I make them look good again?

Thanks!!

I have fondant pieces that I did 9months ago and they still look just fine.
you can do them upto a year in advance if you wanted I guess really or longer.
of course they are going to dry, they will get hard as they sit, I guess the question is are they going to be eaten? when you say sculpture im guessing they are not. for edible pieces i wouldnt do them too far in advance if you dont want them to get too hard, but for non edible it doesnt really matter. I recently did pieces a month in advance. non-edible for decoration only.
fondant isnt like playdough where it dries with a weird hue to them.
they should stay just fine for a very long time. if its going to be months or so though just keep them in a dark place to avoid the colors from fading.
