A lot of folks on the forums are asking about how to glaze windows. I use transparency film specially made for inkjet printers. It is glossy on one side and very lightly frosted on the other. It's almost completely transparent. It's available in the UK from Staples under their own brand name, part number SL5256. I have a long-term 'doll's-house' type office block design in progress. I recently moved house, and have only just found where I left my transparency test print. My method is to print window frames (on the frosted, printable side) which I then use as guides/templates for thin strips of white or coloured paper to give depth to the frames. If you put the glossy side outwards, you get a brilliance which reflects everything in the room - bad for photo-shoots. The duller side looks more like real-world dusty glass. Here's two shots, one with a camera, one with a scanner. I included the brick panels to give a sense of scale - a real print run would omit them to save ink.
