Mitered corners can look great if done right or can be a complete disaster if not. Defiantly not something you want to cut the new guy loose on.
The compound miters have to be absolutely perfect. If the miter angle is off even the littlest bit your corner will start to slowly walk off the wall and is difficult to correct without showing.
I’ve never worked with Hardie Artisan before but have done this with Cedar many times and for me I add 2 hrs. of labor for 8’ of corner.
Hardie does show mitered corners as an option with their Artisan siding. http://www.artisanluxury.com/exterio...erdetail.shtml
