Fun with Illustrator’s Blend Tool
Ever since I read N.Design Studio’s tutorial on how to make abstract lines easily in Illustrator, I’ve been playing around with Illustrator’s Blend Tool to see what I could use it for other than abstract lines. I wanted to show you some of the (really easy) possibilities of this tool, so I put together a small tutorial and I’m going to show you a lot of examples of the kinds of shapes and effects that the blend tool is capable of.
Overview:
The blend tool takes 2 (or more) shapes in Illustrator and essentially ‘morphs’ the first shape into the second by creating a number of steps in between the 2. If you blend and then “Edit > Expand,” you get paths for all of the shapes in between.
There are 3 different Ways the Blend tool can blend: Specified Steps, Smooth Color, or Specified Distance. We will take a look at all 3 with some simple examples.
1. Blending using “Specified Steps”
The first example is probably the most requested, Abstract lines. I don’t want to steal N.Design Studio’s thunder so here is a link to their tutorial on abstract Backgrounds. It’s easy to do and you’ll see an example below of a shape made by following that tutorial.
2 lines blended with 15 steps, .25pt stroke:
4 lines blended with 15 steps, .25pt stroke:
Once I read that tutorial, I started playing around more with the blend tool on different kinds of shapes. The first few examples will be using the Specified Steps mode of the blend tool. To set the mode, go to Object > Blend > Blend Options, and in the drop down menu select “Specified Steps.” Set a number of steps to be used, and click OK. (I will be using 15 steps for all of the examples shown here, including the abstract lines above.)
Now that you have your Blend options set to Specified Steps, (Note: You can also set the Blend Options by double clicking on the Blend Tool in the Tool Palette) make 2 simple shapes on your artboard. I used a Circle and a Star.
Now you can blend it 2 ways: Go to Object > Blend > Make, or key Command+Option+B (Mac) or Control+Alt+B (PC). You can also use the actual tool from the palette, but I like just selecting BOTH shapes and hitting the keyboard shortcut. Make sure you have the shape you want on top On Top. (this will effect your blend more noticeably when using fills instead of strokes) Here is the result, 15 Steps, 1pt stroke on both shapes:
You might notice that even after the Blend, you still only have 2 paths. In order to get paths for all of the steps in between, go to Object > Expand.
You’ll get a prompt for what you want to expand to. I usually just hit ok with the default (all). Note: Expanding your blends goes for the rest of the examples in this tutorial.
Here is what the paths look like “expanded.”
Here I made the star the bigger shape, and used the same blend settings. (15 steps, 1pt stroke on both shapes)
Ok, remember we are still in the Specified Steps part of this tutorial, and now we are going to play with a few more details. I used the same star and circle from above and made the stroke on the circle 3pt. instead of 1 pt. These are small details, but you can get striking results:
15 steps, with different colors and stroke sizes:
15 steps, with different fill colors: (circle is on top)
15 steps, with an artistic brush stroke applied:
You can also select your paths with the Direct Select Tool (White Arrow) AFTER you apply the Blend and make changes. I don’t recommend doing this if you have an extremely complex blend. It could bog you down. All I did here was move the circle path around after the blend was applied:
Now, I made the 2 shapes overlap before I blended, like this:
15 steps, with different stroke sizes:
15 Steps with different Stroke sizes and Stroke colors:
2. Blending using “Smooth Color”
I don’t use this option quite as much because it is really apparent as to which shape is on top, and it seems to be pretty limited for me as far as uses go, but I’ll show you how it works.
There is no setting for steps in with this option because smooth color assumes you want to ‘morph’ the color, AKA a gradient blend. As an example, I used 4 stars shown below. The smallest being on bottom, and the large blue star on top.
Make sure to change your Blend Options to “Smooth Color” if you are following along. Here is what the smooth color blend of the 4 stars looks like:
Like I said, this option is pretty limited (in my opinion) because of the depth factor, but I have found a hidden gem in my experimenting! Once you have your smooth color blend, if you “Expand” (Object > Expand) the shape, you get an intricate set of paths that represent the steps in between. Then all I did was get rid of the fills, and put a .25pt stroke on them. It’s kind of like a 3d wireframe. Check out the result:
3. Blending using “Specified Distance”
This option is pretty much a mix of the 2 above. Instead of specified steps, here you set a specific distance between the “steps” in the Blend. This has it’s advantages because you don’t have to worry about having too many steps and getting a solid color (unless you go with a smaller distance than your stroke size). Say you set your distance to 15 pixels. . . Illustrator will make a step every 15 pixels, no matter how far apart your 2 shapes are. So it is a good way to control the gaps between the steps.
Again I used a star and a circle. like this:
Blended with 7px distance, both 1pt strokes, different stroke colors:
Blended with 12px distance, both 1pt strokes, different stroke colors:
Blended with 12px distance, different stroke sizes, different stroke colors:
Here, I moved the circle outside of the star and still used a 12px distance, but different stroke sizes and colors:
Same as above, but with an artistic brush stroke (oversized, like 10pt):
These are VERY SIMPLE examples. You can easily take this tool and get very complex, very quickly. (and not as symmetrical as in my examples) I hope you have fun with the blend tool as I have been. I use it more and more each day, and the more you try it, the better you get at predicting it’s results.

Cool! ;) I’ve read the tutorial at N Design Studio, too. But I couldn’t have thought about doing this.. Thanks mate!
I can’t begin to tell you how fascinating and informative this blog is. Illustrator has always made me antsy because it is so powerful, and until now, I have felt unwilling to spend time playing around because I had no idea what I was doing. Through the help and great step-by-steps of this site, I’ve started making some big leaps in my graphic design. Thanks so much.
Blend tool is great. Can you see it being used here?
Oh yeah!
Simone, do you know how the wave effect is achieved in that example?
I’m guessing the distort filter after the blend tool?
~BittBox
cool! I’ll be using this one.. thnx!
fantastic! tanx
I was just playing with the blend tool ealier!
Sometimes you just read my mind >.
This is the most informative site on illustrator I have found. And there are freebies too! I find it better than illustratortechniques.com where they rip you off (you have to pay more than USD100 - overseas subscription for some crappy newsletter). And Dave Cross sucks!!
Hi bittbox,
for the wave effect, you asked about:
when using the blend tool, you can actually modifying the path between the first and the second shape, using bezier curves. when u create a blend with the same object as start and end and you select this blend, you can see that there is a path connecting the centers of the start and the end object. You can use the Convert anchor points tool to pull bezier curves out of the end points and have the blend go along a curved path. this creates really stunning effects :)
hope you’ll have fun playing with that!

…and keep up the nice experiments ;)
So that is how you made the custom brush. cool. I will have to play with this tool more.

Wow brilliant effects and some of those I never would have had a clue where to start. Thanks for the info, I might have to start playing around tomorrow!
amazing! thank you!
The 3D wire frame is something I’ve never though about but its a great look….deff. have to use it soon.
why is that every time i go to this site i have an orgasm of illustrator goodness. Please don’t ever stop!!!
Amazing!!!
Bitt, awesome shapes man. I’m gonna have to try this stuff soon, as soon as clients give me some air.
WOW — I spent almost all day trying to figure out how you made the shapes for your custom brushs — HA :-P . Keep up the great work.
@evalottchen
Thanks! I never even tried that. Awesome.

I’ve got to stop bookmarking each and every one of your posts, and just bookmark your super fantastic blog…
Thanks so much for all the tutorials and freebies!
I’ve done a tutorial about the blend tool, it’s in spanish but it’s very clear.
http://planetoideblanco.blogspot.com/2007/04/espiroserpientes-tutorial-de.html
I found this tutorial very interesting and it reminded me something about working with contour. Sometimes I have to work with Corel(not that I like it but some things HAVE TO BE DONE using Corel in this Company) and there is a tool called “interative Contour” which makes a contour either inside or outside the object. I?ve desperately tried to do objects contour on Illustrator, but I haven?t found a way to do so. If you know something about this, if you can help me finding a way to do objects contour using Illustrator, I?ll be the happiest designer EVER
LOVE IT!! Illustrator has so much insane awesomeness in it just by playing around with brushes and this kinda stuff. Good work!
play, play and play some more.
Do you have to pay to make a blend?
I’ve recently taken an interrest in illustration and this blog is just…wow…too damn usefull. Love the examples in this post, always wondered how such complex elements were made. Keep em coming!
Whao~ that is one amazing find for me. Thanks a hell lot! (Oops, forgive my rudeness.)
Wow! Thanks for opening up my eyes to the ease of this tool. I have used it in the past but your tutorial has sparked some wonderful ideas! Thanks for sharing with all of us.

Thanks, it great to see people experimenting with features, rather than coming to the ap with a preconceived idea of what they’re going to do.
mate, that’s amasing, what u r doing with these effects of blended objects, i have done this already and that’s not a big deal if we think about animating these blended objects. cause i have a problem, that until now i havent resolved it yet, it’s how can we animat these objects in “flash” with conserving the same principle of editing them by illustrator? so, am begging u , if u have a response to my question i’ll be pleased to hear it ! am waiting for it and thx previousely.
