I won't say what these will eventually be used for, but I'm pretty sure people can guess which future event they'll be used for.
They are really simply to make. The rose is merely cutting a spiral and rolling it up. At first it looks totally wrong but if you plop it down on a table and let it settle into itself, it really becomes a beautiful bloom.
These ones are more time consuming. Each petal is an individual sheet out paper which are ultimately glued together. I really think the final product is beautiful and worth the effort.
