Tile trim finish query - Tile Advice

[NewbieTiler99]

Morning all,

I like the finish of the window reveal of the attached. My question is, how do you finish the top of the tile trim? Is it a case of a dab of silicone or something to finish off the exposed edge?

Many thanks

Can either do a 3 way mitre or use L shape trims. 45 degrees on the front two and butt the top trim up behind them

Personally I think you need to use trim on all exposed edges or none at all. For me it doesn't look right in the pic.
