A little help with a pattern

[guido5286]

I'm trying to use 3/4 as the tray top because I am having trouble finding 1/2 board that I can carve in. I want to put a carving on the tray surface. Can you help me adjust the back of it where it will acomodate 3/4 board? I don't think I can post the mpc since this is a project that you buy. Here is a picture of what I'm talking about though.
This has a 1/2 inch data I need a 3/4 data.

You can rabbit your 3/4 on router table if there is room for it to be assembled this is one way.Or you can rabbit your board with the carvewright.

When I change the size of the rabbit there is material left over. There are cut paths or something there to take off the extra wood but I don't know how to adjust it to the new 3/4 size. If all else fails I can put it on a milling machine at work and remove the rest.
