I plan on putting up new skirting board (a whole house) and so looked at a few topics here on screwfix. However there is one thing that puzzles me: why use this 'scribing' technique on internal corners? I was all set to cut a load of 45 degrees for every single corner with my compound mitre saw. What could be simpler: measure then mitre then glue?? So here are my questions: 1. Would cutting mitres on all corners be a mistake? 2. Do I need to let the new boards rest for a while to prevent shrinkage when fitted? 3. I've just sanded the floorboards back and they seem to be this nice yellowy pine. My skirting supplier says that he will supply me with 'redwood' - will this be a good match, given that I don't plan on gloss painting? I know nothing of different types of wood. 4. Can I use the same techniques to put up architraving as skirting? Many thanks for responses.
