We installed the curtain yesterday and could not be more pleased! Quality of construction and fit were better than I expected and the bonus is it WORKS! Considerable reduction in echo and noise from the other side; can’t wait to give it a trial on Sunday.


Here’s a photo of the new curtains in our Cornell Kiplinger Theatre.

I just wanted to let you know that the curtains you made for us are perfect!!! They were delivered on time on Friday, and we had them up in time for Easter Sunday. They look beautiful and blocked the majority of the noise. Thank you for building such a beautiful product. We look forward to doing business with you again in the future.
