Drop cloths are a great alternative to outdoor curtains since they're resistant to mold and fading. Plus, you get so much more yardage, dollar for dollar. You can customize your drop cloth curtain with inexpensive latex paint and a pattern of your own design. After drawing your design on a piece of graph paper and working out the measurements, lay your pattern out in painter's tape. Paint between the tape lines, overlapping the tape itself and let it dry for several hours.
