1. create a rectangle
    
2. round the corners with the value 5 and click edit node
    
3. create a node in the center and drag it down
    
4. click on done at the top

write your desired text
i have added small circles and hearts
the green text is cut separately
don't forget to place it separately when laser cutting
you can also use it as an aid to stick it on later 
laser the green text with a score so that you know where each letter goes afterwards

there are 2 circles at the top for the string later on
