Before processing make sure you add two text boxes for the names of the twins into the stars. The project is set to engrave all the details on the plate. In my finished version I changed some parts to score. This was personal choice and up to you if you want to do this.  

To change from engrave to score select object, I then change the layer colour so I can see which is engraved and which are score and then change the settings box on the right to score. Adjust the settings for the material you are using.

Place over the material using the camera on the laser and process the design.

Once the elements have cut remove form the laser and wipe to clean if needed. Using wood glue stick the stars onto the main plate and leave to dry. Once dry add string or ribbon through the holes and tie together.
