Poll: Triangle Or No Triangle Options

I am looking for people to share why they prefer to use or not use a triangle. I know some do and some do only once in a while. So share why you do or don't.

I use a large triangle sometimes, depends what I am doing. I find I use it more on formal occasions and when I am doing something new. It is a good thing to have a place to focus on that is disconnected from my surroundings.

I change things a lot when I do workings, so my triangle is normally tape on a bare wall and sigisl etc stuck onto the actual tape which can be changed as you move through different summonings or rituals in a day, rather than using something with permanent names or sigils on it.
