For my hall, one wall of which is very tall windows, I used new decorators cloths (he long ones that they use to protect stuff). I washed them once and they came out cream and have a soft texture. I then, just for decoration, blanket stitched around the edges. I used embroidery in colours to match a curtain for the doorway into the living room which a friend made from curtains from our previous house. That curtain is nearly 4 m long and she used 4 curtains, with wadding in between.
Thinking laterally can be useful sometimes.
