Ok, I've done something really dumb. I fitted my own laminate flooring. Having never done it before, and only being moderately handy, I had varying degrees of success... some parts are perfectly 10mm from the wall, others are 22+mm. (Next time I'm hiring a professional.)
I didn't want a huge brick of skirting all the way around to cover my mistakes, and I decided I'd forgo beading/scotia, so ordered multiple thicknesses of skirting board. Most 18mm, but two pieces of 25mm for the bigger gaps along certain walls. This is what I ordered--flat boards with a beveled top edge.
Now it's arrived it's suddenly struck me that I don't know how to make those two depths meet in a visually pleasing manner in the corner -- both inside and outside. Like I say, really dumb.
How can I cut these two depths so that they fit together? 45 degrees just isn't going to work, is it?
