First, start by adding a shape, logo, line or symbol that you want to work with to your document window. Below I have added a circle to mine.
Once you've reached this point, select both items. You can do this by clicking and drag your mouse over the two shapes, or by clicking one of the shapes, holding the "Shift" key and clicking the other shape. So now that both of your shapes are selected, move your mouse up to the "Object" menu at the top of your screen, scroll down to "Blend" and when the side menu appears select "Blend Options". Now you have the option of choosing "Specified Distance" or "Specified Steps", in this tutorial we will choose "Specified Steps" Then in the type box to the right we will type in "6". This number determines how many objects will fill in between the two shapes you have selected. Now click "OK" You might notice nothing has happened.
Now go back to the "Object" menu, scroll down to "Blend" and when the side menu appears, select "Make"
As you can see, Illustrator has filled the space evenly with the original shapes. Now, lets make the blended shapes fill up even more space. To do this select the line of circles you have created, move your mouse up to the "Object" tab at the top of your screen and select "Expand". Now you will see that each circle is outline and ready to be blended again. Select the line of circles, copy and "Paste in Front", then drag the new line of circles directly below the first one.
Now, just as before, select both groups of circles and move your mouse up to the "Object" tab, and down to "Blend" and over to "Blend Options". This time we will enter the number "12" into the text field. Click "OK", then go back to "Blend", then select "Make".
And as you can see, Illustrator has continued the pattern vertically.
Now that you have the basics, play with lines and shapes. Even shapes inside of shapes. Then, once you've got it down, play with the "Warp" options with your patterns. This tool can be a lot of fun and very useful.
Hope you found this useful in your Illustrator adventures.
