Question about stacked round pans for wedding cake

Howdy.

I have a wedding cake for my ex brother-in-law this weekend and the bride asked for a round tiered cake with sunflowers and daisies. Other than that I have free reign.

I planned on just doing a 10", 8", & 6" but I've become quite a bit more comfortable with stacking and fondant covering and what once seemed like a huge project doesn't anymore. The cake even seems a bit small to me?

I have read that a lot of ya'll like to have a three inch ledge but the only pan sizes I have available are the 14, 12, 10, 8, & 6, all 2" in height.

My question, would a double (layer) 14", triple 10", double 6" look okay? I'm ready to step out of my comfort zone. Or should I just add an extra 12" layer to the 10,8,6 for a more sizeable cake? She asked for a three tier but I'm sure she wouldn't mind the extra layer, especially if they want to save the top one for their anniversary. I would like to have a larger ledge to work on also but I'm worried 4 inches may be a bit too much?

I plan on arranging the flowers like the pic but leaving off the dots and adding a ribbon border. I'm still working out having small folds at the bottom edge of the cake when I smooth the fondant, ribbons cover that well for me!

And since I have your attention, my square pans come from Wilton. They do not stack well! The edges of the corners taper out a bit and it takes a lot of work to make the cake square. Is there a "more stackable" brand?

I appreciate all input in advance, thank ya'll kindly. - Brandy

She told me about 100 guests would be attending. Even if they save the 6", add in the groom's cake and either option will feed the guests. (Also having a dessert table).

I don't have a 9" pan or I would definately do the 12",9" & 6". I was just wondering if the 4" ledge would be to much so I'm glad to hear you've seen this done and like it.

Thank you very much.

I attatched a picture but it didn't take. I apologize, I hope this works. She found it on Vibrant Bride.

Audrey, ty! I found a set of five 2" pans for just under $70.00 at Global Sugar Art. I'm looking forward to trying these out.

Myra, your cake is very nice, I do like those sizes together. Thank for sharing.
