Arrowheads
Let's start with a basic effect, the Add Arrowheads. Use the Pen Tool or Line Segment Tool to draw a straight line. Go to Effects > Stylize > Add Arrowheads and choose a style.
Appearance
The great thing about using Illustrator Effect is the ease of changing its appearance. In the Appearance palette, click on the Add Arrowheads layer, now you can easily change the result by selecting different arrow style. This effect is very useful for drawing diagrams.
Without The Effect?
Without the effect, the arrow shape will get distorted when the line is stretched. With the effect, I can easily adjust the length of the arrow without distorting it.
Round Corners
Draw a rectangle shape, go to Effects > Stylize > Round Corners and enter a radius value.
Without The Round Corners Effect?
Round Corners is one of my favorite effects. It is my essential tool for designing icons. Not only it can prevent the round corners to be distorted when I stretch the object, it also saves me a lot of time. Could you imagine how long it will take to draw these perfect round corners without the effect?
Zig Zag Effect
Draw a straight line, go to Effects > Distort & Transform > Zig Zag and enter a value for Size and Ridge Per Segment.
Wavy Line
Draw a straight line, apply the Zig Zag effect, select Smooth Points, and you will get a symmetric wavy line.
Badges
Draw a circle and apply the Zig Zag effect with the setting as shown and you will get a badge shape.
Play around with the Zig Zag options and you may get these shapes:
Pucker & Bloat Effect
Draw a circle, go to Effects > Distort & Transform > Pucker & Bloat, enter -55% (Pucker), and you will get a diamond shape.
Draw a polygon shape, apply the pucker effect, and you will get this shape:
With the same object, change the Pucker & Bloat option to 70%, and you will get a flower shape.
Transform Effect
The example below shows how I can duplicate 12 copies of the object (in increment of 30 degree angle) with the Transform effect.
Play around with the shape and Transform setting, you may get the following:
Roughen Effect
With the Roughen Effect, I can make the trees look more realistic.
Scribble Effect
The example below shows how you can create a sketchy effect combining the Scribble and the Roughen effect. First apply the Scribble effect (Effects > Stylize > Scribble) and then apply the Roughen effect as shown.
Sketchy Icons
If you are constantly using the same effect, it is wiser to use the Graphic Styles to save time and maintain consistency.
After you've done the inital sketchy style, drag the object to the Graphic Styles palette to create a new Graphic Style.
Now, select the object(s) where you want to apply the styles. Then, click on the Graphic Style that you've just created. Change the fill and stroke color if you want. Don't forget you can also apply it to text, which remain editable.
Conclusion (There Are More…)
I've only showed the basic Illustrator effects. There are actually more cool and useful effects. Don't be afraid to explore the effect menu and experiment with the other effects such as the Warp and 3D.
