Go on amazon and search "thermal blackout curtains." The grommet top one is great because they are very easy to open and close. They come in different lengths to fit your window. I find that if you mount them high & close to the ceiling, it will block out the light ever better. Same goes for making sure you extend wide beyond the width of the window. You can use on any kind of rod. bed bath has decent/cheap choices. Also we went with a dark color because a lot of the reviews comment that the dark ones block out light better. And the material is quite nice & not cheap looking.
These are what we have as well. Love them! The Navy in DS's room keeps it really dark. I went with beige in our room and it's good, but not as good as the navy for mid-day sun (ie, nap time!).
