In this design video, learn what types of window treatments are best for various styles of windows. Tall Palladian windows and arched windows can often be difficult to dress with window treatments, due to not wanting to hide the beautiful arch. Palladian windows should not be dressed with a window treatment below the arch, as it bisects the window. Panel length is also discussed, with floor length panels or panels that barely break on the floor being the preferred length for most situations. This video also gives tips on where to install drapery rods and window treatments in rooms with tall ceilings or low ceilings. The rule of thumb for most fabrics is 2.5 (or 2 1/2 ) time fullness, while sheers or silks are sometimes made at 3 times fullness or more. Grommet panels may only need 1.5 (or 1 1/2 ) times fullness. The size of the rod also is important. Larger rooms, tall ceilings, or tall windows can require fatter ( larger diameter ) rods. A wall of French doors or bay windows can also pose window treatment dilemmas. This video includes many design and installation tips and tricks to dress various window styles and sizes, including tips on where to mount rods for drapery panels and other types of window coverings.
