"Wanting a program that looked like it was bordered in gold, I called WPD and a staffer went through all the designs and sent me many samples to choose from. I ended up selecting a color that was not on the custom color card, but was used in one of their designs. It come out exactly how I wanted it to. Design wise, a staffer took the time to take this design and give me other design choices- one of which I loved. I made numerous changes along the way and he responded immediately. Couldn't have had a better experience."
