I have a large curtain which I am hoping to split into two panels and hang. It is already double pleated and in good condition with blackout lining. I think it needs to be split into two with a little trimmed, but the height should be okay. A quick measurement is about 4 m wide and just below the triangle portion would be 240 drop. I believe the curtain used to cover a 480cm bay window with 248 drop.
