I saw a tutorial on how to make this (huge) rosette and decided to try it. In fact I made two of them because te first paper was too thick. As usual, I left it for a while and yesterday I thought, why not to make a layout on top of it (as seen in the tutorial) and here it is.
More details and the tutorial on my blog. http://lizzywurmann.typepad.com/my_weblog/
