I needed a 166cm drop for my new net curtains, and had to buy 183cm as the next one down was 160cm. I have never had to alter nets as much as that before, and whereas before I have taken a tuck and stitched it to the channel at the top, I think this will be too much fabric and will look odd. I cannot cut and rehem the bottom as they have a scalloped edge. Any bright ideas from someone with experience of this?
