I recently stripped my entire staircase down to the bare wood with the intention of keeping the newel posts, bannisters and handrails plain wood and carpeting the actual stairs. However all the various components are different shades of wood ranging from very light pine to a rosy warm reddish brown and all shades in between, perhaps due to the different woods and different ages. All I want to do is have everything a similar shade, but without using woodstain, is this ever going to be possible? If so, how do I do it? Really confused by this and don't know what to do with it. Any help very much appreciated, thanks!
