Just over the past month, there have been several explainations on the board about this.
Let me put a few pointers to watch out for.
I recommend 2 layers of substrate (particle board usually)
Beware of self-edges that hang down so low that you can't open the drawers.
Screw the substrate to the cabinets from the underneath. If you do it from the top you will have a heck of a time removing them later, and you make your laminate surface subject to pits from your screw heads.
Alternate your substrate seams. (on a corner, do the bottom layer seam on one side, then do the top layer seam 90* to it on the other side of the corner so they interlock)
Take your time!
Buy a quality router and a professional bearing laminate cutter bit. Worth every penny.
Practice on scrap first. Get good at it, then do the real stuff.
