How do you get it?
Any special tricks?
How thick is your fondant?

Thanks!

I use a fondant smoother, you can pick one up at any cake decorating supply.

I roll my fondant usually about 1/4-1/5 inch thick. I would also suggest that you start from a really nice base cake because if the cake is crappy, then the fondant work wont turn too well. I always use a fondant smoother but let mo tell you, there's this lady on youtube named Andrea and she never used a fondant smoother but her cake is amazingly smooth and clean.
