I found the lamp shade a “royal pain” to assemble. They give you two hoops (with velcro) and a rolled shade.  The “seam” is thick  ( the seam now faces the wall).  If the pole wobbles or doesn’t stand straight, you need to tighten the pole segments more.  (Yes, you have to assemble a pole).
Why did I keep it?  It’s very pretty and modern looking.  It looks like its picture (and the pole seams are barely noticeable).
