Creating Line Drawings in Adobe Illustrator

One Grumpy Dude

This is one grumpy dude. He was created in Adobe Illustrator with the brush tool. I don’t use the program a lot, but when it comes to “inking” my drawings, I find it very useful. Here’s an in-depth look into the making of this cute little grandpa guy including:

  • How to place a sketch into a new document
  • Some digital drawing tips
  • How to fix little mistakes after you’ve drawn your stroke
  • Ways to finish and color your drawing



Preparing to Draw

I start by placing my sketch into a new Illustrator document. Go to File–>Place. Find your sketch file. Before you click OK, make sure the box that is marked “Template” is checked. Notice that your sketch has been placed on its own layer and has automatically been locked and changed to 50% transparency.

Get your tools ready. The default brush set will not do for most artists. Create a variety of brushes to use for your drawing, or open up ones that you have saved. For more about creating and modifying your brushes, see my brush tool tutorial.

My brush palette features round calligraphic brushes in different sizes.

Laying Down Your Brush Strokes

To ink drawings in Illustrator, I like to use the brush tool. I like it better than the pen tool because it better simulates the traditional inking experience and results in looser drawings. Learning to trace a drawing on the computer with a tablet can be really frustrating. You may have to try several times before you get just the right stroke. Just keep practicing using your tablet and eventually you will find yourself pushing Undo less and less.

Some Tips to Get You Started

  • Try “drawing” with your brush, as opposed to just tracing your sketch. Try not to be too stiff and concentrate on staying loose and spontaneous. Try not to break your flow by fixing every little mistake. Just push through, and you can go back and fix it later.

Don’t concentrate so much on making an exact tracing of your sketch. Stay as loose as possible.

  • Use a variety of line. I’ve made a custom brush palette with several different sizes, from a bold 7-pt line to a very thin .5-pt line. You’ll notice that any drawing I do has a balance of thick, medium, and thin lines. Also put some variation within the strokes themselves. Use a tablet and set the brush to be affected by your pen pressure.

Notice the use of both thick and thin lines in my little drawing.

  • Lay down each stroke with confidence. Your lines will be smoother and more stable. Try to keep your strokes longer, instead of shorter. When drawing with your tablet, try to use your whole arm, and not just your wrist.
  • Take advantage of the shape tool for those objects that are just too difficult to draw with the brush tool. I’ll usually resort to the shape tool for circles, ellipses, and squares. You’ll notice that I use the ellipse tool for the table in my Bake Sale video.

The table in my Bake Sale Drawing was done by drawing two ellipses.

Fixing Your Drawing

When you have finished laying down your drawing, you can now go back and fix any small mistakes you may have made.

  • Using the Brush Tool – Highlight the stroke that you want to fix. Now, simply “redraw” a brush stroke over it. Notice that the stroke that you highlighted changes. I find this tip useful for fixing slight curves, or changing the endpoint of a stroke.

  • Changing the Thickness – If a stroke is just slightly too thick or thin, highlight it, then select a different brush. The stroke will change to the size of the new brush. You can also use the Stroke palette by changing the “1 pt” to another value. “2 pt” will double the thickness, “.5 pt” will half the thickness, and so on.
  • The Pen Tool – If need to remove just a portion of a stroke, use the pen tool to add points to the path. Use the Direct Selection tool to delete the unwanted parts.

The ellipses I draw went straight through my pie. I used the pen tool to fix the overlapping areas.

Keeping Your Drawing Organized – Layers and Groups

If your drawing is a bit complicated, it will benefit you greatly if you stay organized. Group paths that are part of the same element, such as a person or an object, by selecting all the paths and going to Object–>Group (or pressing command+G). Now, when you click on one of the paths using the Selection tool, the whole group will be selected. This will make it easier if you need to move or resize your object. It will also keep your Layers palette more organized. If you want to add paths to your group later, click and drag them in your Layers palette. If you need to select a single path, use the Direct Selection Tool or ungroup by going to Object–>Ungroup.

How to Use Your Finished Drawing

You can experiment with different ways to finish your illustration. If you just want to color your drawing with solid colors, I like to use the pencil tool in Illustrator. Create a new layer and place it underneath your drawing. It may also be a good idea to lock your drawing layer, so you don’t accidentally modify it. Pick a fill color and set your stroke color to empty. Draw your shapes underneath your drawing. If you accidentally color outside the lines, you can modify the shapes in the same way fixed your brush strokes. Select your shape, then redraw your edges with the pencil tool to fix it.

Also experiment with different inking styles. Try different sizes and types of brushes to create different effects. In the picture below, I used a very thin brush to add some cross-hatching to my drawing. I liked how it gave it a more hand-drawn feel.

I also like to copy and paste my drawing into Photoshop. The beauty of creating your drawing in Illustrator is that you can resize it any size canvas you like. I keep it on it’s own layer and paint underneath.

This is an example of a drawing that I brought into Photoshop to color.
