Nice heart cutout pattern along with a few for engraving. This allows you to decide what you like to accomplish. You can cut the pattern and overlay on the engraved version, color it, use a background or just keep it as is.
Size your images so that they fit your material. I used wood, the size of the hearts are over 6 inches. You will be laser cutting the patterns and the heart outline and engraving the other. Once completed remove.
You decide what is next.
Version 1 - layered heart. Glue the cut out to the engraved heart and let dry.
Version 2 - color the cut out red (used a marker but painting it may be easier). You can then glue it to the engraved heart.
Version 3- Cut out red paper to the size of the cut-out and paste it to the engraved piece. You will have two hearts. Engraved and the cut-out on red paper.
Extra pieces. In the second canvas are two other hearts that you can engrave.
