this is from when i refaced my cousins stairs. he bought those treads and risers that you just glue over the existing….ya that would have been easy if he didnt buy them the wrong size. his existing tread was too wide which is good for comfortability but not good for the treads he bought. so in the end we had to cut some strips of oak and biscuit joint them to the treads to make the overall tread wider and then walla! they fit, and are virtually seamless. i also put oak veneer over the stringers and oak trim over the tops of the stringers. in the one picture, my dad is staining the stairs not me (im 23 and not balding yet :D) and my girlfriend is supervising!
