Start with a lump of clay

break it into pieces and roll them into a couple balls like in the picture

take the first ball and squish it flat...so it looks like a circular pancake!=]

take the pancake-like-clay-thing and roll it up, as in the picture.

Put your rolled up clay aside and grab another ball and flatten it.

Then take the 2nd flat ball and put it on the rolled up peice, this will create a petal as shown in the picture

Now you keep flattning the rolled balls and adding them to the rose like in the picture.

You can add as many petals as you feel nessasary to make your rose beatiful, lastly as soon as you add all your petals. smooth the bottom to make it look nice, and voila!a rose. It could be used in many ways and it is a helpful bit of knoledge to learn how to do it.
