There are a few things you need before starting to make flyers in Illustrator. First, you will need a piece of paper on which to draw your flyer’s layout. You can use any kind of paper - A4 or even A3 - but it is best to choose something that is easy to print on. Next, you will need some basic shapes and features for your flyer. You can use rectangles, circles, triangles, and other basic shapes to create your flyer’s design. Finally, you will need some basic features for printing your flyers. You can use different types of printers - thermal or inkjet - and the most important thing is to choose a printer that is compatible with Illustrator’s print features.
