it's music to my ears! well . . . honestly . . . it's loud and annoying and ear piercing . . . but it does mean my stairs are being refinished! it's the last major inside project we have . . . and i can't wait to see how they look when they are finished! and the sooner the better . . . the sander has been on for maybe 5 minutes . . . and i'm already about to pull my hair out!
