We've just realised that before the scaffolding comes down in our vaulted ceiling kitchen, we should get our (temporary cheap!) pendants hung. Have to hurry as the painters finish tomorrow afternoon & scaffolding has to be removed then. Trouble is we have no idea at what height these should hang. There will only bd two & it's a large room. V bright as has a huge window at the front (SE facing) & two sets of French doors facing East. Not directly over table or island so no chance of bumping heads. Any ideas of a standard recommended height?
