I am looking for ideas on how to construct wooden Window Frames (to go on top of the existing aluminium ones) so I can incorporate blinds that slide up and down. One issue is that the height of the Window is greater than the drop below it, so I can't simply have one blind that goes up and down. Hopefully attached model will show what I propose - with magnetic stripes at top of frame and blind to hold in place and built such that inner blind pulls the outer one up
Any other designs?
