This weekend I finally got around to making a pelmet box for my living room window. I got the idea from this tutorial. Since my window is pretty wide (72 inches), I had to use 3 foam boards taped end to end. I was worried about stability so I connected it to 2 curtain rods (one towards the top and one towards the bottom to keep it from bowing. The whole project took a few hours and cost about $50 for the fabric, sheer curtains, curtain rods and supplies. I think it really makes the room look more finished.
