Years ago I used a tension rod on my teacher's bookcase. Tension rods don't need any additional hardware installed and are a snap to use! I didn't use it on the children's area because I was hesitant about it falling with frequent, less than careful, use and I didn't want it to look like the children couldn't use the books freely. It WAS GREAT for hiding the mass of things in my bookcase, though!
I am contemplating doing mine with velcro tape. What I am going to do is attach one side of the tape on the top of the shelf, then the other on the top of the fabric I am hanging. I figure this way, if the fire inspector comes around, I can always very quickly rip it down without damaging it.
attached curtains to large wooden cubbies before. I bought some light weight denim fabric from Walmart, used the "iron a hem" strips to actually make the curtains ( I can not sew at all), and viola! I had curtains for my cubbies.
Next I bought 2 inexpensive curtain rods (from Walmart as well), used a drill to attach the brackets into the wood cubbies, and then finally hung them up. I have had the curtains on for almost 10 years and they are still in great condition.
I know this is more detail than you probably needed, but just though I'd share what I did. If you want to use your shower curtain, instead of using a shower rod, I'd look into getting a curtain rod instead. Hope this helps!
I am doing this right now, and have done it for several years. Like the previous post said, cheap curtain rods from Wal-Mart (approx $4-5), and then I get the white plastic hooks that have self adhesive to hang the rods on. Sometimes the adhesive isn't strong enough, but I've found hot glue works very well! Good Luck!
It worked great. I have built in bookshelves all the way across one wall under the windows. I covered the areas of the shelves I did not want the kids to get into at the time, and then removed the curtain when I wanted them to use those things. When they were through, I just stuck the curtain back up. I used the same fabric to make valances for the windows and put them up with tension rods.
