<p>At JHU, theres no window curtains. Since I've been sleeping my whole life with window curtains, is there any way to block the light without drilling holes to install a curtain?</p>
<p>My sister made curtains out of bristol boards. Not only did they work well, but they look very unique. She used black and white bristol boards, cut them into smaller, manageable pieces (2 or 3 per board), and taped them together so they can fold. She also made a little hook or something to hold the folded curtains in place.</p>
<p>at basically any home supply store or discount store (think, bed bath and beyond, target, etc) you can get something called a tension rod. it holds curtains just like a normal curtain rod would, except instead of being mounted to the wall with screws and hanging kind of above the window, it fits inside the window frame and holds itself in place with no screws, nails, or anything sticky--just tension from springs inside of it. of course, this'll only work if you have a window that's kind of sunken into the wall, so that the rod has two surfaces to press against, but it worked perfectly in my dorm last year.</p>
<p>fastfingers, I'm at JHU too. I'd love to hear your success story! I got fined last year at Wolman.</p>
<p>melanieeek's right, tension rods are great. We used them both years in the dorm and they work fine.</p>
<p>I made my own curtains last year, and hung them with a tension rod. Making them is much cheaper, you can make them to whatever dimensions your window is, and whatever look you want. And it only takes a couple minutes. And then tension rods are about $3.</p>
<p>Tension rod is the way to go. If you don't have the inch or so of space you need of depth inside the window, then just buy some of the 3M Command Hooks. They're adhesive, but if you put them on and take them off correctly, it doesn't leave any mark. I bought some this year (BB&B, but places like Target, The Container Store, Lowes, Home Depot, Staples, etc sometimes have them) and tried one out on my wall at home and it worked fine and left nothing on the wall. You could then just put these on the wall next to the window and put the tension rod across so it sits inside the hooks.
If I were you, I'd buy both the tension rod (call your housing division to get the width of the window) and two of the hooks. If you don't need the hooks for the window, you'll easily find a use for them elsewhere (hang up bags, hats, towels, clothes, etc)</p>
