I did modern calligraphy on a set of place cards for a party.
My process is easy:
1. I receive the list of names.
2. I do 2-5 test cards and send them to the customer.
3. The test cards are approved by the customer (or there may be requests for corrections.)
4. After the approval, I do all the cards.
5. I send the invoice and it is paid.
6. I send or deliver the cards.
7. The customer and the guests have a great party.
