Its a challenge to find a white max blackout curtain so I  thought Id try these out.  Compared to the bright white framed mat you can see they are close enough.  They  block all the summer heat and light on my western facing window.  The soft fabric hangs beautifully.  Well sewn - evenly matched -  i have found so many curtains are not no matter what the price. And I  love the unexpected phlange of fabric above the rod pocket!
