1. Create the Art Brushes
When creating a linocut print, artists use special tools to carve designs into a linoleum block. The raised (uncarved) areas of the block form the image. The carved linoleum block is covered with ink, then printed onto paper or fabric. Because the artist removes material from the block to create the image, this is called a "subtractive" or "reductive" process.

Step 1
We want to mimic the shapes of the cuts that a gouge tool makes. Then we'll use those shapes as the basis for a set of Art Brushes. To create the shapes, choose the Blob Brush Tool (Shift-B) and double-click it to bring up its options.Input the settings shown below. Note: If you are not using a graphics tablet, the Pressure setting will not be available. Don't worry, you can still create the shapes. An "Accurate" Fidelity setting will result in more detailed and rougher shapes, which is desirable for a hand-carved look. The Variation in size will allow you to draw a stroke that varies in size, depending on the amount of pressure you use with your graphics pen.

Step 2
Draw three or four strokes with the Blob Brush Tool, pressing down harder on one end and using a lighter touch at the other (if using a graphics tablet), resulting in a tapered shape. If using a mouse, double back on one end to make the resulting shape thicker. You can also adjust individual points to modify the final shapes. The Blob Brush is not technically a brush, but it's great for quickly drawing loose vector shapes.
Step 3
Select one of the shapes you just created, then click the New Brush icon at the bottom of the Brushes panel. Alternately, you can drag the object into the panel.

Step 4
In the dialog box, give your new brush a name, then enter the following settings: The Width can be set to Pressure if you're using a tablet, or left at Fixed if using a mouse. If set to Pressure, you can vary the width based on the percentages you choose in the two sliders. Choose Stretch to Fit Stroke Length in the next section. Below that, make sure the directional arrow begins with the wide part of the shape and ends at the narrow part. Lastly, set the Colorization method to Hue Shift. This is important, because we will be changing the color of the brushes in a later step. (For more on how Colorization works.)
Step 5
Repeat Steps 3 and 4 with the other shapes to create more Art Brushes.Step 6
We'll now create a thin brush to look like it was carved with a v-shaped gouge. Choose the Line Segment Tool (\) and draw out a horizontal line. Increase its weight to about 4 points. From the drop-down menu in the Control Bar, choose Width Profile 3. You can also access width profiles from the Stroke panel.
Step 7
Create a new Art Brush from this new stroke, as you did in Steps 3 and 4.Step 8
Keep this stroke selected and apply a Roughen effect by going to the Effect menu to Distort & Transform> Roughen. Enter the settings below.
Step 9
Once again, drag this object into the Brushes panel to create a new Art Brush. At this point, your Brushes panel should look something like the image below:
Step 10
Many linocuts have marks in the negative space. That is, the area around the main subject matter. We can simulate this effect with a few more Art Brushes. Using the Pen Tool (P), draw some simple shapes like the ones in the image below:
Step 11
As before, create new Art Brushes from these shapes.Step 12
Unlike a real printmaker, we don't have to make each mark by hand. We can create Art Brushes that contain multiple strokes, and use them to apply texture to larger sections of our illustration. Using the Blob Brush, Pen Tool or any other drawing tools you prefer, create a few groups containing multiple objects. Then create Art Brushes as before. Below are some examples:
Step 13
Let's create one more Art Brush, for a lighter texture. Start by double-clicking the Pencil Tool (N) to bring up its options. Use a fairly smooth setting, and click the Fill new pencil strokes option.


2. Create the Pattern Brushes
Relief prints, such as linocuts and woodcuts, can only produce one solid color at a time. There is no way to get a tint or shade of a color in a one-color print. To create highlights, relief printmakers use crosshatching, or a series of small, repeating strokes. For this technique, we'll create some Pattern Brushes.Step 1
Draw a few pencils strokes as you did in Step 13 above, but this time, make them vertical.
Step 2
Take the Blob Brush Tool (Shift-B) and connect the pencil strokes at the bottom. The result is one shape, as in the image below:
Step 3
If we were to use this shape as it is to create a Pattern Brush, there would be space between the individual components:

Step 4
Just as you did with the Art Brushes, select the object and click the New Brush icon at the bottom of the Brushes panel. Or just drag the object into the panel.The Pattern Brush Options should look something like the image below. You only have to concern yourself with the Side Tile (highlighted). Tick Stretch to fit, and be sure to use Hue Shift as the Colorization method.


3. Save Your Brushes
Step 1
Now that you've put a lot of time into creating all these brushes, you can save them to use in any Illustrator document. Click the flyout menu on the top right of the Brushes panel and choose Save Brush Library. You will then be taken to the Brushes folder inside the Adobe Illustrator folder, where you can give the set a name and save it. It will save as a native Illustrator (.ai) file
Step 2
When you want to use these brushes in another document, click the Brush Libraries Menu at the bottom of the Brushes panel, or click the flyout menu at the top right, and choose Open Brush Library > User Defined, then choose your brushes.
4. Draw the Branch
Since a linocut is a reductive process, I'm going to start with a black shape, then apply the brushes in white, so they look cut out of the black. The remaining black areas will "print."Step 1
I'm using this Creative Commons photo as a reference. You can of course use your own photo or sketch. Draw a simple branch shape, using the Pen Tool (P). Even though my reference photo does not have a branch, I'm going to add one for more visual interest. Make another path that follows the top edge of the branch shape. This will be the highlight.
Step 2
Select the highlight path and apply the Pattern Brush to it by clicking its thumbnail in the Brushes panel. Change to stroke color to white.
Step 3
If the stroke is too big or too small, you can change its point size in the Stroke panel. Alternately, you can click the Options of Selected Object icon at the bottom of the Brushes panel and change its size from there. This lets you fine tune the appearance of the selected path.

Note:
You may be wondering why we didn't just create white brushes to begin with, rather than having to change the color to white. Simply because it's very difficult to see white brushes in the Brushes panel. In fact, if you prefer a lighter user interface, you would not be able to see them at all!
Step 4
Draw two more paths inside the branch shape. Apply one of the texture brushes to give a woody texture. If necessary, adjust the scale of each path. Keep it simple. The finished branch is below.
4. Draw the Bird
Step 1
Draw a silhouette of the bird. Fill it with black. You can do this quickly, using the Blob Brush Tool (Shift-B) or Pencil Tool (N). It doesn't have to be precise, because we're going for a hand-drawn look. Lock the silhouette shape.
Step 2
Just as you did with the branch, draw a line for the highlight of each leg. Adjust the scale of the stroke if need be. In the example below, the width of the stroke is 0.5 point, and the scale (in the Stroke Options) is about 90%. Note: To change the scale to an absolute value, you'll have to choose Fixed from the Scale drop-down menu.
Step 3
Start adding some white strokes to the head of the bird. Remember to think like a printmaker: By adding white strokes in Illustrator, it's as if you're removing sections of the black shape to create white (non-printing) areas of the print.
Step 4
Using some of the texture brushes you created in Section 1, Step 12, draw some strokes inside the wings. We're not trying to draw every single feather here, but just create a nice texture.


Step 5
For the tail feathers, use the Pattern Brush we created in Section 3. You can use the Width Tool (Shift-W) on any kind of stroke, including Pattern Brushes. In the image below, I am making the top of the stroke wider:

Step 6
As you did in Step 4 above, draw some textured strokes for the breast feathers. Try not to make all the strokes look alike. You can click the Options of Selected Object icon on the Brushes panel, then tick the Flip Across button for a different look.


Step 7
Add some black strokes around the outline of the bird, to break up the smooth surface of the silhouette.
5. Finishing Touches
Step 1
Using the negative space brushes you made in Section 1, Step 10, add some strokes around the outside of the bird. This will add some "process marks" and give the illustration a more handmade look.
Step 2
Now we'll add a watercolor wash to the bird's breast. Click the Brush Libraries Menu icon at the bottom of the Brushes panel. Navigate to Artistic> Artistic_Watercolor.



Step 3
Using the Rectangle Tool (M), draw a rectangle around the illustration where you want to crop it. Copy the rectangle. Select All and go to the Object menu to Clipping Mask> Make.
Step 4
Paste the rectangle you just copied in front. Apply any of the linocut brushes to create a frame around your "print". Add some more small marks around the edges and in the negative space for a more authentic look.
