If you’re in need of protection from the prying eyes of the unknown that lie just beyond your window somewhere in the darkness, or, you’d just like to make a change to your place, then you have come to the right place 
All you need to know to create your own window coverings is just a scroll of the mouse away.
I recently had the opportunity to share some of my DIY knowledge on apartmenttherapy.com, take a look at the instructions below. If you decide to try your hand at it, please, let me know how it goes.
Tools:
1. Measure the width of the window and cut 3/4″ thick screen molding to size. If you’ve got a saw at home that’s great but I would suggest making your cuts at the store where you buy the molding. It’s easier to transport when the pieces aren’t 10′ long and hanging out the back of your car. Most places like Home Depot will supply a small hand saw and tape measure for your convenience.
2. Measure the height of the window. Using a straight edge (extra piece of molding will work), mark lightly on the the back of your fabric the length (plus a 3/4″) and the width of the window and cut out. If you’re using a striped or patterned fabric be sure to place your cut molding in the center of the pattern so that when you draw the curtain the edges that meet will match.
3. Lay your pre-cut molding a 3/4″ shy of the top edge of your cut fabric and fold the excess over. Secure with heavy duty staples every inch and a half.
4. Cut a piece of twine double the length of your fabric and lay over the center of the molding.
5. Either very strategically on your own, or with help, hold the molding tight to the window casing (staples facing up). Hammer in finishing nails at either end first and then follow with one in the center and any additional that are needed. The heavier your fabric, the more you should use.
6. Tie the loose ends of the twine in a bow/knot as high or low as you like. The higher you get the more gathering will occur with your fabric. Once you’ve secured the twine you can adjust the folds. The softer the fold the better, if they’re too perfect your curtain will look like an accordion. Just lift and gradually set down letting the fabric settle on itself.
That’s all there is to it! Of course, if you’d like a more finished look and you know how to sew you can add a hem to all four sides of the fabric before you staple the fabric onto the molding. Just be sure to account for this when measuring.
Because this is such an easy way to add color/ texture with the added benefit of privacy to your place you can switch out the fabric as often as the desire strikes you. If you want to change the look replace the twine with ribbon. I myself was struck with the inspiration to change this weekend while visting the fashion district downtown. I discovered, after a long absence, that Michael Levine has hundreds of awesome, affordable fabrics that would work fabulously in my own place.
We're not saying that mauve is a bad color. It's great, if used in the right application. The right application does not, however, happen to be a one piece toilet and a giant whirlpool tub. Mauve has no place in a thousand square foot bungalow built in 1944, no place at all. So we're fixing that...
