Any ideas on how I could make an edible grass skirt to go around a round cake?

I would probably use fondant and my clay gun to make strings... You could just pipe it using...maybe a 12 round? Anyway, here you a bump!

Maybe the grass tip? Does it have to be buttercream or fondant? I've seen where they've taken fruit roll-ups, the sheets and cut it in strips too.

If you have a pasta roller thing, you can run fondant through for spaghetti.

I've used the grass tip before.
