Newbie Q: Inside-mount shades on vinyl windows
All I've ever done before with windows is hang roller shades and cover them with a valance. Now I'm trying to hang rice-paper blinds inside a window--but I discovered that the window has no depth to make that possible. However, there is about one inch of what feel like plastic between the top of the window itself and the trim around the window. (This may be a filler strip of some kind to make a standard-size replacement vinyl window fit into a non-standard size opening.)
Can I attach a shade to that piece of plastic somehow? Adhesive? I know it wouldn't be really inside mounted, in that the shade would project out from the window into the room, but it would keep the shade all within the outlines of the trim. I would really, really like not to hang the shade from the trim or outside it; I want the lines of the trim surrounding the shade without interruption.
Thanks for any help!
