@ultinator Mark the trim where the mitre is meant to start and at 90 degrees, fold the mark right over the trim face to the other side on the top two pieces of trim, then mitre at 45 degrees into the centre of the trim from both sides of the trim starting from the same line you have marked. It's easier to fit the top two pieces first to then help you find where to mark your vertical piece and simply apply the same principle to the vertical piece, draw one line at 90 degrees right over the face of the trim and cut into the centre at 45 degrees from both sides of the trim starting at the same mark. Make sure to use a small square set off your window frame which should be plumb to align your piece of trim that is on the window revel, this will make sure the mitre joints meet correctly and also a quick touch with a file will remove any burr left from the cut and you'll finish up with a nice 3 way mitre.

Nice 😕

this was just an example maybe a bad one but was trying to suggest to mitre the trim from the wall to top trim rather than mitre the top trims together just looks better, also i think that a novice at tiling would find it very difficult to do a three way mitre

Three way mitres aren't easy, how about taking your quad trim back and swapping it for straight edged, simple to finish the corners 😉

Everyone will have different preferences, however the op asked for instruction as to how to do it, I've obliged but that doesn't mean I'm suggesting a novice should be tackling them 😉

I'd get the corner pieces. I don't like sharp corners like that sticking out.

I agree
