Looks great, Ken!
Joker, the pieces are peel-n-stick. Try not to put it down till you KNOW it's where you want it. Peel a corner, hold the rest in place, then pull the paper off. As far as the teak lines go, once you have the template material laid out and taped down, you'll go back around with a Sharpie (they provide a marker, as well) to do all your cut lines. "Match mark" one piece to the next by drawing a line across them. Number each piece. Draw an arrow on each piece showing "forward". Take a few pictures of the whole thing. I've done quite a few of these and by using those guidelines, the teak lines will match up since SeaDek will line it back up as they scan it. Oh, then order the "dry fit" which is a full-size, printed template of what you sent them. Only after verifying everything is good should you actually order it.
