Message: I have a roller blind made of polyester material that is non-blackout (ie translucent). I wish to make the fabric black-out to achieve privacy. Would I be able to cover the tiny pin holes by painting (eg using acryllic wall paint etc) over the fabric. would I spoilt the roller blind?

You certainly could cover the holes with acrylic paint, but wouldn't the shade then be too stiff to roll up properly? I'm afraid that this may not be a good idea.
