Carpentry and Woodworking - Three questions on crown moulding

1) What is the best way to end crown moulding when I come to a stopping place? Have the moulding turn 90 degrees and end in the wall? _______]

2) What height should I make the crown moulding for a 9 1/2 foot ceiling?

3) And finally, anyone have any great pics/designs for a nice build-up crown moulding?

Many thanks in advance,
Steve

1. I would do a 90 degree return into the wall, Cut a 90 short of the end of
the wall and then cut a short facing 90 into the wall.

2, I would suggest always putting crown moulding at ceiling height.

Hope this helps Bill :)

Thanks Bill.
The site link was very helpful, as well as the moulding return. What I meant (but didn't explain very well), was how high (like 4" or 12" - probably too high) would be a suitable height for a room that has 9 1/2' walls. I read where if the moulding is too big, it makes the room look smaller.

I would probably stay around six inches total on a 9 1/2 foot ceiling height. One way is to use a stock 4 1/4" crown moulding from Home Depot or Lowes drop down a couple inches put up a small trim piece and then paint the crown moulding 2" wall area and small trim piece the same color. This gives the appearance of a much larger overall crown.
