We plan to build a covered patio in 2016 and wanted to soften the look with outdoor curtains but still wanted sunshine to filter through.  As many places as we looked, they were either far too expensive, not the right size or too thick.  These panels are amazing and since we caught a big sale on them, the price was much more in line with what we wanted to spend.  They are very light, however, so if you don't want them blowing everywhere and potentially getting damaged, add weights at the bottom or create lower panel attachments to a post - this is what we plan to do upon installation.  Shipping was exactly as the company disclosed.
