It's from Graceful Cake Creations.
This looks like a life-size picture, judging by the rose petals.
You could measure it to see.

The scrolls look like freehand piping to me.
As for the draping... I like to make sure the rectangle to use the drape is wide enough so i have plenty of fondant to gather. Also, I like to roll it around 1/16"-1/8" thick depending on the length of the drape. I tend to adjust it sometimes to how long the drape has to go from one point to another. I find if I roll it too thin, the pleats don't have enough body and sag too much. Too thick and it doesn't drape gracefully. I dunno if this makes sense.
