I went back and searched the forum but could not find an answer to my question. I have 15 smallish (10" x 20") wall pieces that I want to try fuming. Since they are meant to hang on the wall, the finish needs to be on all sides. Question is: if I stand them up in the tent will the finish penetrate to the flat surface they are standing on. I've seen that the fuming process goes pretty deep with industrial ammonia - which I will use - so might it get to the area covered because they are standing on it? If not I'll have to come up with a way to hang them - can't build a tent big enough to lay them flat on stand offs.
