Is this for exterior or interior use?

GN Builders: She said it was for her living room so it would be for interior use.

Thank you Architectural Novice! Probably I wasn't awake yet :-).

@ Molly McManus, you can get MDF molding from the same supplier who sells wood it will save you some money.

If you want composite molding there is stores that sell them like Home Depot, Lowes, etc, or you can order them online from places who sell specialty millwork, but most of the time they come with a precut length of 8' and you could end up with a lot of splices (depends on the room size) and have lots of waste...

If you not doing the work yourself and plan to hire a contractor, you will be better off having him supply the molding and you can have the wood for a lot less then what you can buy.

Good luck
