These curtains are thick, blackout material. But they are not heavy, stiff, or bulky. They hang nicely and are sewn with back tabs and supporting ribbon for use with drapery pins. I am hanging my set with rings. They have a slight sheen to them. With the double wide option, these were a perfect fit for my 3 panel windows. These would also be nice hanging tall over patio or french doors. I will be purchasing another set in the future for another set of windows.
