Nice heavy weight. Well made. Does a good job of blocking out the light. The grommets are 1 9/16" inside diameter. I was able to use a 7' x 1 3/8" wooden rod without a center support since I wanted to use this single panel for a sliding patio door where the curtain could slide to one side. I selected a wooden rod with a little bow in the middle, so the weight of the curtain would then straighten it out. It worked out pretty good. It arrived it good shape and on the expected date. The wrinkles disappeared once I put it in the dryer with a damp cloth (low setting) and then hung it up.
