Boo Perfect Paper CurtainsMade of black crepe paper (no longer just for prom and local parade floats), the curtains ad a bit of an ominous touch even to a yellow tinted room. I did these a few years back in the old apartment. They work best with windows with no coverings or with blinds hung inside the frame/molding. The stretchy quality of crepe paper is more forgiving than traditional tissue paper. Use double sided tape to attach them to window frame. Transfer tape would also work. This is a very inexpensive way to add more gloom to your Halloween festivities. I used the edges of different sized plates and saucers to create the scallops. To match the ones on the end, I cut out the first one then traced the outline onto the second one. Folding paper in half will also produce mirror images. If you have ebony hued furniture they create a dramatic mood.
