The Bamboo Blackout Roman blinds are made of very thin (matchstick thickness) bamboo, in two tones (with the darker placed every 6th line). On my screen it appeared to be made of thick strips with a slight gap. So I was a little surprised once I saw it, but still liked the overall look so kept them.
I like the convenience of the self-holding (when it stays open without tying)feature - pull the cord a little to the right and it stays put.
Relatively easy to shorten where needed. Only challenge came when I had to shorten to wooden strip at the top, that needed some thought to alter and re-cut the slot the metal support goes into.
One box arrived open, missing the metal support. I email them and the next day I received a replacement. Excellent customer service.
