I posted this within a previous question, but thought I'd put it out there for others to see and give input. We are considering changing our spindles to iron ones, but not sure what style would be best or combine 2 different types or how that works? There are other plainer styles available as well, these were ones I liked. Thanks.
what the stairs look like now.
