My house is just about to go on the market and I'm having real problems fixing my vertical blinds. They are quite old and some of the plastic weights at the bottom of the slats have come loose. I have tried various types of glue and sticky tape to try and secure the slats (which appear to be made of nylon or similar), just so they look okay/reasonable but nothing seems to work. I don't want to go to the expensive of replacing them as the new owners might not even like this style. Any tips greatly appreciated :)
