A: Yes! There are roller cassettes designed just for this purpose. Most people looking to install roller shades like the low-profile design and want to maintain that look throughout their window decorations. Roller shade cassettes are simple and give a sleek contemporary way to hide the roll at the top of your window. They also come in all kinds of colors that allows you to match either your trim or the roller shade itself. Both Hunter Douglas and YourBlinds carry low-profile roller shade cassettes.
If you want something less modern, you might also want to consider a conventional valence. Roller shades work great with existing drapes just by hiding the roll under a matching valence. You won't even know it's there!
