Started out with drawing in photoshop to ensure all lines are crisp and easy to convert into a water jet program when it is time to cut. 

I used the existing shape that was cut by a previous water jet operator, set up the home, uploaded my own design, and cut the new shape on the table.

This is the new cut that was made from the drawing I did in Photoshop. 

I cleaned it up a bit on the polishing wheel.
