Hi guys, is there any such thing as a DIY Holland Blind kit? I have a small bathroom window that needs a blind - it cops the blazing afternoon sun - but the window doesn't seem to have a standard-sized aperture - 1020 (H) x 720 (W). The blind has to be installed 'in-frame'. I don't want to go through the costly process of getting quotes, then being charged an arm and a leg for such a small installation. Any ideas? Thanks, Orlando
