Let's open a new document in Illustrator (File > New) and enter the size 600 px by 600 px (but you can choose any size you want). I used the CMYK color mode to use it for printing.
Now select the Rounded Rectangle Tool, and create a rounded rectangle without fill, and with a black stroke. The radius can be changed by pressing the arrows up or down button, while keeping the left button of the mouse held down.
Open the Appearance and Stroke palettes and create multiple strokes as shown.
Select a Rounded Rectangle and go to Object > Transform > Rotate, then enter the angle 90 and press the Copy button.
Select both rounded rectangles and apply Object > Expand Appearance, and then Object > Expand.
Select the Live Paint Bucket (K), then fill a few areas with white as shown below
Change the fill to black and fill in areas as shown.
To convert the Live Paint group into individual paths press Expand on the top tool panel. Now group (Command + G) all the objects.
Select the Ellipse Tool and create an ellipse without a fill and a black stroke. Align them along the vertical and horizontal as shown.
Select the ellipse and create multiple strokes (see Step 2).
Select the ellipses, go to Object > Expand Appearance, Object > Expand. Select all objects and apply a Live Paint Bucket (K) (see steps 5 and 6).
Select the Live Paint Bucket (K), set the fill to black and fill in areas as shown below.
I congratulate you! The first simple ornament is ready!
The second way. Now we start weaving the ornament from three simple elements. For convenience of work go to View > Show Grid. Create the first element. Select the Rounded Rectangle Tool and create a rounded rectangle without fill and a black stroke.
Select a path and add two points as shown. Select the Scissors Tool (C), cut the left and right new anchor points and delete the right bottom part of the path.
Create multiple strokes.
Create the second element. Duplicate the first element. Select the Scissors Tool (C), cut the top anchor point and delete the right part of the path.
Select the Pen Tool (P) and add a new point as in the image below.
Let's create the third element. Now duplicate the first element. Select the Scissors Tool (C), cut the top-left anchor point and delete the top part of the path. Drag the top point up as shown.
Select all elements and go to Object > Expand Appearance, and also apply Object > Expand.
Duplicate, rotate elements and start to make an ornament.
The second simple, Celtic ornament is finished!
The third way. Let's create a more difficult ornament. Select the Ellipse Tool and create an ellipse without fill, and a black stroke. Duplicate the ellipse and move it up and to the right.
Select the Scissors Tool (C), cut the top anchor points on both ellipses. Now drag the anchor points downwards a little.
Select the left point of the left ellipse and the right point of the right ellipse. Go to Object > Path > Average, and select Both. Then apply Object > Path > Join.
Drag the handles and we will give a more complete view of the curve.
We apply a similar action with the right point of the left ellipse and the left point of the right ellipse.
Open the Appearance and stroke palettes and create a multiple stroke as shown.
Let's create illusion that the path crosses. Select the Scissors Tool (C), cut the path as shown below.
Let's disguise the places where the cuts are.
Select the path, and place it above all.
Select the blue stroke in the Appearance palette and press on the Round Cap in the Stroke palette. Now the cut areas are disguised. Group both paths (Command + G).
Select the group and go to Object > Transform > Reflect, and press Copy.
Select the first group and rotate it 45 degrees (Object > Transform > Rotate). Select the second group and rotate it -45 degrees.
Change the vertical sizes of the groups as shown.
We'll now apply techniques from Steps 24 and 25. Remember that at the crossing of two paths one is to pass above and another passes below, moving further on that path that was from above we should hide this line on following crossing downwards. Observe alternations below to avoid errors.
Ungroup all paths (Shift + Command + G). Scissor part of the path and go to Object > Arrange > Bring to Front.
Select all objects and go to Object > Expand Appearance, and then Object > Expand. Select all blue elements of the first shape and apply a gradient as shown.
Now select all blue elements of the second shape and apply a gradient.
The final celtic knot is ready! The last set of techniques allow you to create knots of any complexity.
Here is an alternate version of the final series of techniques. Have fun creating your own!
