I'm getting close to my wits end. Fondant is driving me there. I can NOT seem to get my fondant covered cakes smooth. Here is a picture of my latest fondant covered cake:

Right then, the lumps and bumps weren't so noticeable but when I delivered and set up the cake it was bulgy and the little tear/stretch marks were a lot easier to see. I see cakes with beautiful crisp edges and sides and want mine to look better... 

Help please!

Are you saying that you are in business selling fondant cakes that are sloppy and unprofessional?

if so then stop.

or are you a hobbyist making things for people for fun and to celebrate their happy occasions with them?

then keep at it, try a different fondant, practice your skills, get new tools, study, and keep plodding on. You have a million and one things to learn yet.  If your cakes taste great that's important while your fondant skills are low.  It doesn't mean that you CAN'T do it, You just don't know HOW to do it (yet).

You have a nice color use, a good design, and your sock monkey figurines are adorable.  If you should give up is your decision to make.  But you are way way better at this than I am right now. IMO

I mainly make cakes for friends and family and when I have made them for customers, I've never done fondant. I've been told that my cakes taste good a lot, but I don't really like cake all that much.  

Is it your fondant that is lumpy or your buttercream/ganache under the fondant.  If your base layer is not smooth then you are never going to get your fondant smooth.

All you need to do is KEEP practicing.  The more you do, the better you will get.  When you look at many of the gorgeous cakes with flawless fondant, you are also looking at a huge variety of:

homemade or commercially prepared fondant?

what recipe homemade?

what brand commercial fondant?

buttercream under fondant?

marzipan under fondant?

chocolate ganache under fondant?

how thick is the under-coat of buttercream, IMBC, SMBC, marzipan, ganache, etc.?

mud cake, fruit cake, sponge cake, American cake mix cake, modified American cake mix cake, etc.?

how LONG did a particular cake take to create?

Is it a REAL cake to be consumed, or a DUMMY cake for display?

Fillings?  (only about a zillion possibilities)

How thick/thin/slippery is the filling?

Is there a dam?

Was the cake allowed to settle?

was the cake frozen & filled & covered with fondant.....

Well.   You get the idea.  The information provided in your 3 posts (about 15 sentences) is only enough for anyone in cake decorating to make a guess.    Cake decorating perfection doesn't just magically appear after a few months.  Compare this to learning a new language.  You don't become fluent in another language "in a few months".  However, with cake decorating, while you are learning, you and others get to eat a lot of tasty cake!

Here is a tutorial thread with  superb links for information freely available on the internet.  Hope some of this information is helpful.

AYes. Hours and hours and hours. You will get there eventually, and you will be frustrated as hell along the way. But it will happen

Thank you all for your replies! I think I need to work at getting my buttercream smoother and rolling my fondant slightly thicker. 

and practicing on a LOT of cakes too!
