When you're preparing a session...

Thats the right idea! When you are DMing, you are the boss, so if you do something wrong, and they call you on it, just look at them and confirm what it is you said.

I like to do stuff like that on purpose.

It keeps the players that have memorized the books on their toes.

"the figures running at you are wearing armor that looks to be made from paper."

"Their armor is made from paper?"

"Yup. Why?"

The paper armor was from the Order of the Tome. Protectors of an ancient magical library. The armor was fashioned from paper, but acts as armor. Plus you get the benefit of it being light as paper. It is good for PC's that want a light armor, but want real protection.

Everything went great, I've still got it!

Thanks all.

I wouldn't be too nervous about it. Even if you mess up a little, your players won't likely notice.
