I genuinely don't know what to think.
I paid for these blinds to be made and they are just hooks screwed through the material into a thin wooden batten sewn into the top.
I person I bought them from was very shirty with me when I said they weren't right and said this is a common way of making Roman blinds.
He says to hang them I just need similar little hooks on the window frame that the blind sits on.
I think this will be very flimsy and may stay up for a month or so. Also the blind cord is very thin, more like thick cotton. What do you think?
