I recently had a woman email me that wants three different cakes for a joint birthday party for her, her daughter who is turning 21, and her son who is turning 22. For the daughter she wants a red velvet cake with shades of pink. I sent her some ideas and we decided on a 2-tier round cake (8 and 10 inch) with cream cheese frosting with fondant accents in multiple shades of pink. Stripes on the bottom tier, circles on the top tier, and a fondant loop bow on top. Similar to the pic in this link but all in pink:

Then she told me she wants a football themed cake for the son and a tiered cake (yellow cake with buttercream) with "all shades of green" for herself. I like the design that another CCer used for the flowers on the cake in the link below which I would do in shades of green.

So I'm thinking a 2-tier square for her cake. I'm not sure if I should do both tiers with the flowers or do a different design on each tier. I thought about doing scrollwork before I saw the other flowers but I don't think the scrollwork would allow me to use enough shades of green.

So I was thinking maybe scrollwork on the other tier but not sure if that would go with the flowers. I don't want to use the same designs as the other cake (circles and stripes) but am having trouble coming up with another design that would go with the flowers.

I was also thinking of doing a fondant ribbon and bow around the base of each tier. Any ideas for the other tier or should I just do the flowers on both?

what about doing it like this cake for the top and the bottom tier doing what you suggested?
