Renee, Yungbin and I tried several methods to hang up the fabric to create a blackout curtain. The best method was to fasten basswood strips to the edge of the fabric, fold the fabric over twice, and then nail the curtain to the ceiling (through the fabric and basswood). This method looks nice since the fabric is rolled along the basswood and since you can’t see how it is fastened to the ceiling. We plan on folding the sides in and ironing them to give the curtain clean edges.
