8. Creating a border
1. Use the Rectangle tool and create a box that is 1-inch from all sides of the page. (If you’ve already created a color background you can use the same box, just make sure it is 1-inch from all sides of the page.)
2. Highlight the rectangle you have created using the Selection tool. (You may also use the selection tool the adjust the size of the rectangle at this time.)
3. Click on the Stroke box located on the tool bar.
4. Then go to the Swatches Menu or the Brushes Menu, for a desired color or pattern you wish to use for a border. If these menus are not on the desktop, then go to Window > Show Swatches or Show Brushes.
5 Go to the Stroke Menu, which should be on the desktop. Again, if this menu is not on the desktop go to Window > Show Stroke. Adjust the weight, which is the thickness of the border.
Finished!!! Good luck using Adobe Illustrator.
