Curtains were free of odor, folds, or wrinkles, and could be hung immediately.  To be honest I thought they weren't going to work.  The color was so light (ivory) and the material not as heavy as expected.  Once I got them up, it was like somebody turned the lights out. Great blackout curtain!!! I know they're not rated as thermal, but just blocking the light has kept that room cooler.  Very pretty design and affordable.
