Broken Blind/Fly Mesh

Pippah45

l accidentally broke off one side of the blind yesterday(moving cushions) is this going to be a replacement job or are they repairable?  I say "broke" but the side bit has ripped off its screw and come out of the top rail and all the tension has gone so
not looking good really . I suppose on the bright side I might be able to replace the dreaded concertina with a better one.  Any
advice appreciate.
