Howdy, that looks I've a right ball breaker of a job! Did you freehand each step or did you make up a template? I'm quoting for a job just now that specifies 200mm stringer with cove to one side, aluminium edges to the other and double tread stair nosings. There's 32 bloody steps in the flats but then theres another 2 maybe 3 blocks after this one!!
