Shelf, mirror and picture hanging in Scarborough often starts on a staircase. The back-splits and side-splits around Wexford, Bendale and Agincourt have those short runs of wall between half levels, and that is exactly where people want the family photographs.
Getting it right is layout more than muscle. I measure the stair rise, set a line that follows it, and space the frames so the group climbs with the steps instead of fighting them. Everything lands in a stud or a proper anchor, and the wall is left clean when I go.
