Need to fit a venetian blind using top fixings and the opening is not square by any means. The top horizontal part (skimmed plasterboard) of the the opening dips / is lower in the middle, with each end rising up higher, maybe between 5 and 10 mil difference. Also, one end of the top section might be higher than other end. Maybe I just fit it and it wont be noticeable, but are there methods to make the blind sit better?
Thanks,
Thanks,
