Woofgang has provided an excellent answer but I'll just point out one thing that you'll need to consider:
As with all one-way mirrors (or should that be 'two-way mirrors'?; the terms are, rather oddly, synonymous!) the person on the darker side can see through the glass/film, but the person on the lighter side can't. So, in daylight, you'll be able to see out but your neighbour won't be able to see in (because you'll be in the relative darkness of your craft room, whereas the other side of the film will be illuminated by daylight).
However at night your side of the film will be brightest (because you'll using artificial light), with the other side being darkest. So your neighbour will be able to stare in, without you even knowing that he's there (because the mirror will be reversed and you can't see out).
I used to work in a railway station's Customer Service office. We had no problems with the public seeing that we were inside; indeed, we wanted them to know where to come for assistance. However somebody 'up high' thought that it would be a good idea to install 2-way (1-way?) film on the windows.
During the day the customers couldn't see that we were waiting to help them (because they couldn't see in) but at night we couldn't monitor the drunks on the platforms (because we couldn't see out of what, from the outside, was now a brightly-illuminated 'fish tank', visible to all!)
