I use some of the pretty shower curtains on my windows as my curtains. I have a white lacy type on the bathroom window and looks great. Long ago when I got my first home, we used a nice double layered shower curtain in my dining room. The material ones work best. In a pinch, it's a frugal idea until you find the curtains you like or want.

Shower curtains for porch windows.
Shower curtains were quick, easy and inexpensive for my porch. I have 12 windows in my enclosed porch. We installed white 1 inch and 1/4 round wooden curtain rods and used the white plastic round curtain hooks. Once up they do not look like plastic curtain hooks and match the rods nicely. The finish on the fabric shower curtains is what I wanted. This type of fabric is not only great if we forget to close the windows if it rains but it also seems to repel dust better than a cotton type fabric would.
I went with the soft white color since the interior and cathedral ceiling and beams are shades of white. The shower curtains are easily opened to let in the light or closed to filter the sunlight. Each curtain was purchased at Wal-Mart for $10 each x 12 is quite a savings. the size was a perfect fit for the double hung windows. It also creates a summer sort of nautical look. Very easy care.

I have discovered that shower curtains can make great window drapery. Not the plastic liner stuff but the nylon fabric.
I have five large windows close together in my living room, and love to change my decor often. However getting curtains for all five can cost a bundle!
