I hang mirrors professionally and think that jmm1837's reply is spot on. For a client of mine I would hold it up and make a decision in situ when the client thinks it 'looks right'. That said. I would probably start by recommending a position where the base of the mirror is close to being in line with the top of the bell jar. You want it to be high enough to not make the mantle top ornaments look cluttered. But you may also want it low enough to reflect a tall flower arrangement. Hope this helps.

Hi Damian... is this question for an existing home or a new build? Are you able to show a picture of the space you are talking about or draw up a rough plan? Would be interesting to get a better idea of the area you are talking about so we can offer more accurate suggestions for you :)

They all look good, but it all comes down to clearance. How low is your ceiling? How tall is your tallest visitor? How long is the light fitting? Will the light fitting look good if it is close to the ceiling, or will it look cramped and foreshortened? When I moved into my current home (with a taller ceiling than yours), I got an electrician to hang a row of pendants down the length of the hallway so they would be 5 cm taller than my family's Uncle Colin (who was by far the tallest regular visitor). Now twelve years later, Uncle Colin has passed, and my little boy (who was six years old when the pendants were hung) has grown to be 192 centimetres (6'6") and needs to duck everytime he goes to his bedroom. I need to get my electrician back to make all of the pendants shorter, but the proportion of cable length to shade won't be as nice. Best of luck, Dr Retro of Dr Retro House Calls

What IP rating is required for lights over kitchen sink. I’m wanting to hang a pendant light but understand restrictions apply re placement and type of light due to hanging over water zone. I need to determine what type of light I can buy
