I realized after attempting to install these blinds that they're for windows without a sash. They are intended to be attached to either the glass (with tape) or screwed into the window rails. However, I want to make them work. I'd like to attach them to the jambs so that I can still open and close the window when needed, but the blinds needed to be cut to be narrower to fit within the frame. What material can I use to attach the plastic portion to the jamb? I intend to screw it in, but I'm not sure what I should use. Would wood be best? Or PLA? or maybe cardboard?
These are top-down, bottom up shades from Ikea - Hornvallmo
Thank you!
