Here is how my 14 foot Hyside looks after I re-laced it. I used four lace pieces, starting each at the middle of a side and going to the middle of the other side, around the front and the back. (You will finish with the four ends at each middle). I can't say what the specific ins and outs were for each lace at the front and back to get it to be the way it looks. It did take some thinking about the pattern I wanted to achieve.
Make sure you do it with wet laces, and pull them tight as you go, especially at the front and back. The front was very important to me, to minimize the space that water can get through to splash a passenger.
It helps to have someone with you, to pull a lace end through a grommet after you start it as you keep pushing it through.
