The more densely woven areas will cover the horizontal framing of the windows, with the lacy open weave in front of the glass. In situations where more privacy is required, there can be a larger densely woven area for the bottom section of the panel, with the lace sections placed higher up. Photos of your window(s) accompanied by detailed measurements will enable me to design specifically for your needs. I recommend natural or very pale colored yarns for best effect, and to minimize fading from daylight. These panels are designed to be hung in a permanent position, but can be moved to a flat surface for gentle cleaning with a vacuum cleaner.
