Welcome to Cake Central.
Poured fondant is normally used for petit fours, very small cakes and cookies. It is generally somewhat transparent and doesn't cover well.
I have used poured fondant but only on mini cakes and they had been covered in fondant first. Have a look at my website www.cakeoccasions.co.nz and look for Shana (green) and Laura (Denim blue). Quite easy to make but a bit messy. Cheers.
