These are wonderful. I have 10 foot ceilings so I had to have them altered.  I have them puddled on the floor and nearly to the ceiling. Have them on 4 windows in the house. Adds and elegant and finished touch. They don’t serve a function, they just frame the windows. Gorgeous. The wrinkles don’t ever really fall out all the way (and I keep my home quite humid). But that’s linen for you!  I’ve considered switching to a heavier weight fabric in Winter but haven’t ever done it yet.
