I have selected the Bali layered shade and I’m being told it can only be mounted either in the back of the valance or top mounted. With it being a arched window I won’t be able to do that. The only suggestion the installer have is to mount it above the window which would clearly look silly with all the other windows being inside mount. What other options don’t have without having to go to a different product? I’m in love with this shade and really don’t want to go to a cellular or shear shade which is what they suggested since I can side mount those.
