It is entirely possible to make flyers, posters and other marketing materials in Microsoft Word. An advantage of using Word compared to Google Docs is that there are a lot of free templates available to download specifically for flyers and posters. As many workplaces have Word installed, this method of making marketing materials would best suit anyone who is familiar with Word and is okay with the limited features. You can subscribe to Microsoft 365 for a monthly fee. Use Word’s flyer and poster templates to help you get started.
