First, determine which ornament you'd like to create. If you're doing the 3D ornament, select those objects and send only that job to the laser.
NOTE: Since the thickness of the acrylic can vary, you can resize the interlocking notch space in the 3D design.
For the inlay style, select an acrylic color and send the job to the laser. Send it a second time using a different color acrylic and you can mix and match the colors!
