Place the wooden tree branch slice on the baseplate.  Set the auto measure (A with ruler icon on top right).  Next set the processing area (the flag that looks like a golf flag upper right area to the left of auto measure).  I used the circle.

Pick which image you want to print.  Make sure that they are set to engrave and the other image to ignore.  Place the image and size it so it fits within the processing area you set.

check the processing area by pressing framing.  This also helps you double check that the other image is on ignore.

Process.

Flip the wood and repeat with the other image (if double-sided is desired).

Place basswood piece onto the baseplate.  Set the auto measure (A with ruler icon on top right).  Next set the processing area (the flag that looks like a golf flag upper right area to the left of auto measure). 

Process,

Get glue and put glue on the rectangle ends.  Slide into the thin slots and let dry.

You can spray the wood with polyurethane for protection.

Enjoy!
