"Instead of buying trim to frame doorways and windows, my husband and I use 3-inch-by-8-foot furring strips. They're inexpensive and come in bundles of six at the home center. The strips can be left as is for a simple, clean look, or you can use a router to create more decorative profiles. So far we've used them for a window, doorways, and baseboards in our foyer and living room. They give us a look that's a little different and unexpected."
