We are updating our entire staircase to get rid of the terrible carpet and faded wood. A few years ago, we updated the floors with solid hickory but left our 4" oak trim throughout the house. We want oil rubbed bronze iron ballusters and plan to do the stairs, railings/newells in hickory. This costs thousands more than oak. Do we take the plunge with hickory to match the floors? Or should we use oak or pine treads and risers and paint the steps and skirts and do hickory railings/newells? This is a huge deal - I don't want to make a costly design mistake.
