Bay windows let it in a maximum amount of light and create a natural window seat. A scarf valance is a wise choice for any home with a bay window because it accentuates the window without blocking too much light. They're also fast and simple to install.
Hang the fabric of your scarf valance so it forms a slight semicircle shape on each of the three panels of your bay window. The key for this look is keeping things as symmetrical and identical as possible. For example, measure each semicircle you create out of the fabric, making sure they all have identical heights and widths. Adjust the scarf valances so the panels of fabric you have hanging on the far left and far right sides of the bay window are exactly equal. This overall look will emphasise your bay window's harmony of shape.
Just as centring your scarf valance perfectly creates a distinctive, balanced look, not centring it can also give it a striking, artistic look. For example, drape the fabric of your scarf valance so it creates hanging semicircles of different sizes. Work from left to right, with the section of scarf valance above the far left panel of your bay window making a slight semicircle, the scarf valance above the middle panel of the bay window making a somewhat larger semicircle and the final section of scarf valance making the largest hanging semicircle.
Part of the appeal of scarf valances is they don't block a lot of light. However, for people who want to maintain a higher level of privacy, layer sections of scarf valance on top of each other so they filter more light and hide more of the inside of your home. For example, select two scarf valances of complementary or contrasting shades, such as sheer blue and sheer green fabric. Start with one piece of scarf valance and drape it along the bay window, creating centred hanging semicircles. Lay the following piece of scarf valance over the valance you already hung so it overlaps but does not cover completely the first valance. The finished effect gives you more anonymity, more texture and a dynamic colour scheme.
