If your entryway could use some sprucing, try adding a new door knocker. Choose a style like the one at left, which is anchored through the door using sturdy threaded rods. Not only will it have a tighter grip than surface-screwed styles, but hidden mounts will also give it a more polished look than exposed screwheads. Measure rails and stiles to avoid ordering a too-big model: The knocker shouldn't infringe on door panels. For best effect, mount it about 5 feet high.
