For a look that is both custom and classic,
Keep in mind that roller shades do have a fairly wide gap on each side, so adding a soft drapery panel framing your window will give you optimal light control. The duel roller shades offers the best of both. Use a sheer fabric for day-time lighting and an opaque fabric behind for optimal light control. This is essentially 2 roller shades, one behind the other, with a cassette valance to complete the treatment.
As with all window treatments, there is the issue of light gaps on the sides – the widest of all being with roller shades. One way I have solved this problem is with the addition of a light block on the insides of the window. It does not need to be elaborate. I use a small vinyl strip, usually purchased from the local hardware. I recommend a small amount of glue to secure it to the sides – just enough to keep it in place. The shade comes down behind the strip and that covers that pesky light gap.
The Harmony program offers more than 47 fabric styles – choose the same fabrics for your vertical and horizontal treatments when you combine Designer roller shades with SKYLINE Gliding Window Panels. This gives you the best of both – cover wide expanses of window with gliding panels, then the smaller windows with coordinating Designer roller shades. Complete the look with a cassette valance on both treatments. If your style is both contemporary and minimal, choose Hunter Douglas roller shades and gliding window panels – available in both 11” and 17” width vanes.
