Popular Pattern Types: Brick Repeats

In the brick repeat, every second row is shifted halfway in the horizontal direction. You can create the brick repeat with the Simple shift symmetry , by dragging the top or bottom side of the control path horizontally, when the mouse pointer changes to the horizontal shear cursor .

You can also use the Half-turn symmetry to create a fractional brick repeat with a smaller horizontal shift in which every other row is rotated 180°.
Similarly, the Mirror & glide symmetry and the Perpendicular mirrors & glide symmetry let you create fractional brick repeats with additional mirror symmetries.
With the Simple shift and Half-turn symmetries, you will typically use both horizontal and vertical blending to create seamless brick patterns.
