What You'll Be Creating

In this tutorial you'll learn how to create an intertwining trellis design from scratch using grid layouts and lining up a narrow, rotated rectangle according to said grid layout. It's a basic, classic pattern that's easy to achieve if you break the shapes down to a simple, repeatable section.

1. Setting Up the Grid Layout

Step 1

The measurements in this tutorial are fairly precise. I worked everything out in a document sized 140 pixels by 193 pixels at a resolution of 72 dpi. For larger designs or a print-ready version versus a web-ready version, you'll have to work out the size conversion on your own. 

Create a New Document according to the specifications below and let's create our grid!

Create a New Document

Step 2

Go to View > New Guide Layout, select both Columns and Rows, and enter 2 for Number of each. Hit OK and move on to the next step.

Set up the grid frame

Step 3

The second Guide Layout involves the option for setting up lines according to a margin. Enter 27 px for each section and hit OK.

Setting up the first set of margin defined grid lines

Step 4

The final set of grid lines are defined by the following margin settings:

  • Top: 60 px
  • Left: 42 px
  • Bottom: 60 px
  • Right: 44 px
Define the final set of grid lines

Step 5

See below for the final grid layout. There are 7 Column Lines and 7 Row Lines in total. Lock Guides (Alt-Control-;) and use the Paint Bucket Tool (G) to fill in your document's background layer with gray (#707070) or the color of your choice.

Fill in the background and lock your grid

2. Creating the Pattern

Step 1

Use the Rectangle Tool (U) to draw a long, narrow rectangle measuring 262 px by 13 px. Set the fill color to yellow (#ffef42) or the color of your choice. Make sure the Rectangle Tool is set to Shape in the Options bar.

Step 2

Select your rectangle shape and go to Edit > Transform > Rotate and Rotate the shape 45°. Use the Move Tool (V) to align the edge of your rectangle with the intersection of the fourth column line and the third row line.

In the Layers panel, right-click and Duplicate the rectangle shape layer. Go to Edit > Transform > Flip Horizontal. Align the flipped rectangle with the same intersection as before. Note how the two rectangles form an "X" that is aligned to the center column line.

Rotate and align rectangles

Step 3

Once again, Duplicate your rectangle shapes. This time, align them with the fourth column line and the fifth row line. Note how the third and fifth column lines align with the intersections of your rectangle shapes.

Align the second set of rectangle shapes

Step 4

Duplicate the diagonal rectangle shape again (make sure this one goes from the top left to the bottom right) and align it in the top right of the document. Note the arrows pointing to the intersection points of the second row line and the sixth column line.

Repeat for the left side (making sure the diagonal rectangle goes from the top right to the bottom left) aligning the intersections with the second column line and the second row line.

It helps, when lining up your shapes, to nudge selected rectangle layers around with the arrow keys, especially when aiming to be precise.

Align the shorter rectangle shapes

Step 5

Finally, repeat the smaller lines at the bottom of the design. Align the right diagonal rectangle with the sixth column line and sixth row line. Align the left diagonal rectangle with the second column line and the sixth row line. 

Align the final rectangle shapes to complete the design

Step 6

Under View, deselect Extras (Control-H) and go to Edit > Define Pattern. Give your new pattern a name. Create a New Document of 800 pixels by 600 pixels and use the Paint Bucket Tool to test it out. If the pattern is not seamless or the rectangles were misaligned in any way, toggle Extras on again and move individual diagonal rectangles as needed.

It took quite a bit of trial and error to make sure my grid lines and rectangles were aligned perfectly before writing this tutorial up, so you should have a perfectly seamless design if you aligned your rectangles to the grid layouts created at the start of this tutorial.
