I don't know that I've seen one like this, but I can picture it so clearly in my head! I have a friend that requested a 3 tier wedding cake and my only direction is to make it pretty with some spring yellow. My first thought was a white cake with little yellow rosebuds piped all over (sort of a calico fabric look). Has anyone seen a cake that looks something like this? I would love to show her a pic of what I mean, but I couldn't find one in the gallery or online anywhere. TIA for any and all help!

If you google wedding cake images there's thousands that you can look at and one of them has to be what you're looking for
HTH

Here are some with delicate yellow themes. (Sincere apologies, I have no record of the bakers/bakeries to credit these, as my computer crashed recently and I have only numbered images now. )

Here are a few that might help get the ideas going.

I think I know exactly which one you are talking about. It is one that is on the box of either the round or oval set of Wilton pans. Is it this one?

I googled my hiney off and looked at thousands of pics, but didn't find exactly what I was looking for. Several of the ones you all posted are very, very close though! Thanks so much!!!!

The first one Antonia74 posted is soooo pretty!
