One of the fun things about cake decorating is that there is no limit to  the kinds of things you can do. Case in point, this teapot cake my  sister and I made for my mom's birthday last fall. I had done spherical cakes before--okay, one spherical cake--but nothing quite like  this, and I was excited to tackle the project. My sister has more  experience with cake decorating in general, but had never done a cake like this before, so it was a new and fun experience for both of us.
First  we baked the cakes. My sister has the 
soccer  ball pan, which is a half sphere so she baked the top and bottom  pieces. Then as she packed them to bring to my house the day before we  decorated, she realized they didn't make a full circle when you put them  together. I baked a nine-inch circle for the middle the next morning  before she arrived.

While my cake finished cooling, we cut out the fondant  flowers for the decorations, and she formed the handle and spout around  some wire. It would have been better if we'd made the handle and spout a  few days earlier out of gum paste, but I was insanely busy that week,  so I didn't get it done like I'd planned. Remember if you make colored  decorations out of gum paste or fondant with the plan to dry them that  you need to put in quite a bit more color than you expect because they  fade as they dry.  We used the 
daisy  cut outs for these flowers, and just put a ball of yellow fondant  in the centers.

Then we filled the layers and frosted the ball. Before  we started the crumb coating, I trimmed a bit off of one of the circles  so it would sit flat on the plate and not roll too easily. We also  trimmed the sides to they would seams between the layers would be  smoother.
We added a 9" round of cardboard between the second and  third layers and put dowels inside the cake to support it so the top  layers wouldn't be too heavy and squish the bottom one. As always, you  have to try to make the frosting as smooth as you can before adding the  fondant because it shows ripples under the surface, but don't kill  yourself over it, since tiny differences in height will smooth out as  you play with the fondant.

We rolled the fondant just a bit thinner on the edges,  then carefully lifted the layer of fondant and worked it in the middle to  stretch it. This might take a little practice to get it to work right  without leaving thin spots where your knuckles pressed against the  fondant. Make sure it looks as good as possible before putting it on the  cake--once you get the buttercream on the fondant it becomes a mess to  start over.

We pressed an indentation into the cake at the level  where the lid should go. In retrospect, we should have carved a lid into  the cake before we frosted it--something to remember for the future.  Then we used buttercream to decorate the teapot. We used tip 
804  for the dots with the 
large  pastry coupler and just put the dots on randomly. We used them to  cover up some of the minor irregularities in the cake, an added  advantage.

We touched our impeccable clean fingertips to powdered  sugar and pressed it onto the dots to flatten them out.

Then we used a clean paint brush (like the type you buy  for kids to water color with. I have a set that is used ONLY for cake  decorating) to spread a bit of water on the back of the flowers so they  would stick to the cake. Fondant sticks to fondant really well with just  a touch of dampness. The bigger flowers didn't stick to the bottom half  of the cake very well because of gravity, but the smaller ones did all  right.

Here's the finished product with the handle and spout  installed. We used multiple pieces of wire to stick them into the cake,  but they were still quite heavy, so in the future I'd use  a thinner  spout--and again, I'd do it ahead and let it dry so I wouldn't have to  worry about the wire cutting through the fondant or gum paste as I put  it together.
We just used a basic  dot to finish off the bottom. If I had it to do again, I would use a lot  more flowers and various kinds along the base to hide the places where  the fondant didn't smooth together perfectly at the base. It's hard  enough getting a smooth finish on a round cake without adding the fact  that a spherical one actually gets smaller at the bottom. Still, we were  pretty happy with the end result.
