This is a variation on the chevron pattern that is so popular this season. This pattern basically involves creating rows of trapezoids, lined up nice and tidy, with the correct spacing in between them. This project is simplified by the use of TeaCup PatternMaker.
Start by making some squares. The stroke weight, dash length, and gap length all need to be the same. The line distance is double those.
Next, add some skew and rotation to the frame. I used -90 degrees rotation, and -45 degrees for the skew.
Copy, paste in pace, and flip horizontally.
Scoot it into place and color it as desired. I like pink, because that is the color of InDesign.
Whatever color you want to use, you'll just need to add it to the swatches panel in order for it to appear in the color choice drop down in the PatternMaker panel.
