You all have been incredibly helpful. I will be running the options by my roommates and figuring out what they're prefer as far as general obtrusiveness etc. goes. I have chalkboard paint on hand to prevent reflections. Everything that's been said is helpful in covering all the details. I hadn't even thought of light leaks around the door, just at the bottom, for instance. Perils of a first darkroom, I suppose.
Thanks so much everyone!
Here is how I do it. I like to be able to go from normal room to dark room in a few seconds. I think it looks okay too. Enjoy.
