All the roman blinds we put in when we moved in here 7 years ago are breaking. The plastic clips at the back of the blinds have all degraded in the sun and grown brittle. I have been hunting for replacement pieces that are the right size to clip onto the crossbars of the blinds. They aren't easy to find. Or rather, those little pieces are easy to find but they are too large to hold the crossbars on the blinds we have. Who knew this could be so tricky?
