So, my question is: is there a better way to do it than rough measurements, followed by many iterations of fine adjustment, to get best fit? Against a hard surface (which this was), a kickboard or skirting board with complet ely faithful reproduction of the contours of the floor can look naff, drawi ng the eye to the unevenness. The trick seems to be to go some way to accom modating the ups and downs, but accepting that gaps between floor and board might be unavoidable for best overall appearance.
I'm aware of bendy profile strips that can be used to reproduce uneven surf aces, but I don't think that one of these would have helped over a 3m lengt h.
What do pros do?
