We are currently having our windows in our edwardian semi restored. We have to choose catchment stays and side fasteners. The choice is extensive and I have no idea what to go with or if it even matters. Biggest choice is, do I go with some form of silver finish (shine or matt) or do I go with a charcole finish that could be painted the same as the window frame? I feel totally ridiculous even asking this! I've never even noticed the fasteners on any windows before, possibly why I don't have a clue! Thoughts ...anyone? TIA!
