Looking at the room they shot the West Elm Branch floor lamp in, did not help. (which, PS I really want that lamp!)
I think it would be easier to DIY this type of trim that lays flat on the wall. Crown moulding is such a beast!
Have you attempted anything like this? Maybe I'll just try it in the dining room and stop there if it's too much work/money. I'm especially drawn to the way the moulding and walls are painted that only makes the moulding look chunkier.
