A: Cellular shades come in styles specifically designed for arched windows and come in the same colors as their traditional honeycomb shades. This means your mother-in-law can find gorgeous cellular shades for the windows in her room and then simply choose the coordinating arched shade.
Like most arched shades, these cellular shades are fixed and immobile. But, since cellular shades come in a variety of light diffusing and light filtering styles, she can find ones that block direct sunlight but still allow for natural light to enter her home. This means she can find coordinating styles, eliminate sun glare, and create a beautiful room all at the same time.
And a lot of cellular brands are available for other odd-shaped windows as well. Including skylights!
