I use printed acetate for this type of window, and all you have to do is make a double line around the sash that you want to "operate", then carefully cut above and below the center, then gently twist it out into position. You don't even need glue.
This doesn't have an operating sash, but you can see how easy it would be to add one.


I did this on the auto plant I built at the Delmarva club, but I don't have any good pictures of it.
