how do I make realistic looking twigs for a camo cake, I have a request for one and I'm stuck. Thanks

I'd pipe them out of chocolate, probably. You could get them pretty thin that way.

I need them to stick in the cake n lay on the cake with the leaves so they need to be hard, so would that work?

If you made them thick enough it would. You could also poke a hole in the cake before you insert them into the cake, so that they wouldn't be the thing making the hole. That way they'd be less likely to break. You could also use a pretzel stick as a base for them, then they'd be sturdier.

You could also use RI. I would lay a small skewer down on wax paper and make your first couple layers and then flip it over and do the other side.

thanks!
