Sorry. I have lost the instructions.. I put in the two fittings with screw in recessed window and trying to trim the actual blind to the size...and although the whole thing fits in, it doesn't fit with the screwed in fittings..if you know what I mean. Am I meant to cut it shorter again and then I put it in and it's done?? or is there more to it, and what am I supposed to do with bead chain connector...??? I have never done this before and DH is non DIY. I would REALLy appreciate some help...before I cut the blind too narrow..
