Hi, I have a bunch of the Free Modular rooms. I hadn't been bothering with them until now. I also have a bunch of teleport arrows that go with the rooms, but can't figure out how to find the one I want to go with the room I am trying to connect or how to connect the rooms. Can someone steer me in the right direction, please and thank you? Hopefully I explained my question well.

in the room, in decorating mode, you should be able to move your arrow and it should show the letters for that arrow. in your inventory when getting ready to decorate, search for arrow and then find the matching arrow with the same letters. you place it in the room or avenue of your choice.
