We are in the process of refinishing the woodwork in our foyer/stairs and dining room. The foyer/stairs look great - chestnut that has been stained with a coat of polyurethane. We are now working on the dining room. The walls are made of beautiful old walnut with a lot of detail. We have tried a few test sample stains with an application of polyurethane. The finish is coming out much darker than we'd hope - hiding some of the detail we've worked hard to bring out. Any ideas for a finish? Also, someone suggested using wax instead of polyurethane. Any recommendations welcome. Thanks.
