For things like flat abstract shapes, grass blades etc.

What do you use? A roller? A knife?

Just curious...

x-acto knife

I use a scalpel (surgical knife)...love it!
You may need to either rub a little shortening to the tip or dip it into some cornstarch to help it not stick as much and make it easier to glide through the fondant without tugging or sticking to it.

Of course!!! That would be perfect... and yay, I already have one of those.

I use a small pair of straight edged scissors for grass.
