Hello @linda20,
Apologies- there are many various ways one can go about designing a sigil (for reference, several methods are explored in the Sigils, What to Do Discussion). Could you please clarify more about the method you are using? What do the full instructions say?
If you share/take a screenshot/picture of the instructions, we can dig in and try to figure out what needs to be done specifically for the sigil-making method you are using 
Blessed be!
