Creating envelopes in Microsoft Word is as easy as printing envelopes by hand. A special tool in the program automatically creates the envelopes for you. All you need to do is enter your return address and the recipient’s address. If you want to give your envelopes a personal touch or format them to match your brand, you can customize the appearance of the text.
