Add notes to an invoice

SUGGESTED

 Been using Peachtree (now Sage 50 Mfg) for years. Still can't figure this out. I'd like to add a note to a customer's invoice. Something like, "1,000 pieces shipped to Ohio; 500 pieces shipped to Colorado". I tried using the NOTE button on the top of the invoice screen but I can't get anything to print out on the invoice. The note could be between line items or below the line items. What do I need to do?
