How do you customise and join vinyl laminate benchtops together from the flatpax range. I was thinking of getting the corner benchtop but I need to attach a long piece to one end. Are the holes already pre-drilled in both the long and corner benchtops. Also, what if I need a shorter benchtop length than provided. Will I have to cut it myself and if I do how do I get that edge strip to look the same as the top of benchtop.
