I've heard brancholoris or plantaloris.

A couple of thoughts... Like the other posts mentioned, an easy way is to use cut up foam core or even poke some holes in blackwrap. There is also another solution at www.shadowfoils.com . They sell inexpensive sets of pre-cut blackwrap patterns in a organizer that fits well into the back of a light case. And since they are made to just clip onto the barn doors, you don't even need a c-stand in your kit.
