Enough text ... I love stripes. I love cake. Here are some pictures.
My expert opinion:
The rolled fondant is my favorite (the first and the last pictures). I also like the idea of having both vertical and horizontal stripes, though that cake looks like a stack of oversized sugar cubes ready for a middle school pyramid project. I would really love to rip the floppy bows off of the brown/white cake, but I am a big fan of the varying stripe size and how the stripes are actually ... in the fondant. I have no idea how cake making works, so that's the best description I could give.
