Curtains - advice to lengthen

[Choccakelass27]

I recently washed my hall curtains and yes, you guessed it they've shrunk!

Does anyone have any ideas for lengthening them? I'm quite good on a sewing machine, so was thinking of adding a panel of a contrasting material to them to lengthen them. Has anyone done something similar - did it work?

They were expensive curtains so I don't want to replace.

Any ideas gratefully appreciated.

Add the panel and enjoy them a few more years. Go for it!
