I'm getting some blinds made but the person who's making them showed me some she's made using black out fabric and they have little holes where she's stitched the blackout fabric to the other fabric and blind structure. It looked a bit odd seeing little bits of light coming through when the blinds were down and I want to avoid it. She's going to investigate a way of doing it without but I thought I would too.
Do your blinds have this? Or, if not, how is the blackout fabric fixed to the rest of it then?
TIA.
