I would like [number of curtain panels] shortened so that the hem reaches [position] when hung. The existing hanging arrangement is [details], and the fittings [will stay / will change / are undecided]. From which point to which point is the finished length measured, does it include the heading, and how does it correspond to the intended position? What site details still need checking, and who confirms the dimensions before shortening begins? I can provide existing photos.
