Cost: $12+, depending on types of window treatments chosen
- spring clamps
- curtain rod
- sheet(s), fabric or window treatment(s)
- rubber bands
You will need two spring clamps, which can be purchased from your local home improvement store for $2-3 each. Make sure they open at least 1" so they won't crush the top rail of your blinds or bend the interior mechanism. I'm using 4" x 1" opening clamps from Home Depot. Place one clamp on each end of the rail.
Shirr your curtain panels onto a standard rod (available at most discount and home improvement stores for $3-5). You can also use fabric or sheets instead of pre-made curtain panels. Sheets are easy to use as curtains because the top hem makes a great rod pocket -- just snip holes in either end and run the rod through. Place the rod on top of the clamps. Use twist ties or rubber bands to secure the rod to the clamps if you wish.
For the top treatment, you will need a long piece of fabric. The appropriate length will vary depending on the size of your window and the look you’re going for. In these photos, I’m using a five-yard scarf valance (bought at a thrift store for $2.50) on a 48" window. Run the fabric through two rubber bands.
Drape the fabric through the clamps. Adjust so it's hanging evenly (or just the right amount of skewed, if you prefer). Secure the fabric to the clamps with the rubber bands.
Run the end of the fabric through a rubber band until the band is a few inches below the clamp.
Pull the band up to the bottom of the clamp, making a loop with the fabric. Secure the band to the clamp. This will form a "pouf" which will hide the clamp.
Repeat on the other side.
If you don't like the pouf look, you can hide the clamps some other way -- big bows or draped scarves, for example. You could even make a hole in the back of a pair of foam skulls and pop those over the clamps. Spooky!
When it's time to depart, you can easily take down your window treatments and leave no evidence.
