I am not super experienced so I need some simple idea.

Its black and white themed.

It is 2 tier - 10 inch and 6inch round. I will chuck an 8 inch in if it will make the effect look better.

I dont know whether to go black then white or black white black or white black white (you get my drift)
I dont know how to hide my seems and what colour for border.

I was thinking a large loopy bow made from fondant on top

Id like to encorporate 6 rose flowers into if I can.

I also have to put their names somewhere.

I just dont know how to tie all this in together (suggests beyond these ideas I will consider too)

It just has to be black and white themed. I need it not too hard for a beginner(ish) but I really want to wow people and it to have impact. Design suggestions please???

Go to the search bar under cake central and type in black and white cakes and scan through the pictures for some ideas

I would cover the whole cake in white, and then use black decorations -- fondant cutouts maybe, or real ribbon, or silk flowers, or whatever in black. Or paint the names on in black.

Because black frosting, honestly, is just not that appetizing. No matter how elegantly done.

Yes, what holly said, black is a bit of a pain to work with! I would think 6 and 10 would look a bit odd, maybe 6 and 9 would be better proportioned?

Here are a couple I've done:

Here is one I did http://cakecentral.com/modules.php?name=gallery&file=displayimage&pid=1471337

I'm not very experienced either. I definately think go with the white cover and black accents.

For mine I made a template be enlarging the invitation and printing it on cardboard, then I used it to cut the fondant. You might be able to do that sort of thing with your roses?

now they are saying that they want black piping over the wilton vines impression mat. Ive never piped before! is it hard...?? lol should I try it or not bother when Im not experienced in it.

If you have never piped before, I don't think black on white is the time to start. Any mistakes that you make will really show up. I f you have to, I would practice first on something other than your cake,
I agree with one of your other posters and use cutters or your roses and not too much black. Keeping things fairly simple and clean make more of an impact on a black and white cake because of the color contrast.
Good luck, and congrats on your order.

I think the sizes are fine. I've done 2 cakes with one tier being 10" and the top being 6" and thought they looked great together.

Your possibilities are endless on a black and white cake. How about some black cornelli lace on the white fondant/buttercream?

So I have kinda two ideas.. what do you guys think?

2 tier. White fondant covered. Black fondant ribbon around the bottom seams of the tiers. The bottom tier white part imprinted with the impression mat, then a large loopy black bow on top. Their names or initials on the cake board or on the top of the top tier.

Either that,

Or exactly the same except on the white bottom instead of the impression mat, I do black royal icing dots in a diamond patter. What do you guys think? or any variation?

Hi Here is a polka dot cake that I did for a small wedding celebration.

It was a miniature cake and very simple to do.
