Can you add side channels/brackets to existing oller blinds?
I'm trying to get roller blinds fitted into my movie room, but most companies I've spoken to have suggested light blocking set ups that just look very bulky/ugly (https://ift.tt/2Lh8TXG). I prefer to get an open cassette, so that the front of it can be covered in fabric to match the blinds. Is there a way for me to get the regular blinds installed, then figure out a more subtle way to block the light? via /r/DIY https://ift.tt/38zeVMl
