Design Elements in Photomontage - from Illustrator to Photoshop

Using at minimum 1 repeating shapes with 1 color create a design that will be
incorporated into your Photomontage (view the Grid, Rulers & Guides and Smart
Guides to help you). You may elect to add more elements such as text and other
shapes to try different designs. Consider using symmetry or asymmetry as well as
other design concepts.

Select and copy the vector designs and/or text from Illustrator and paste it into
Photoshop Photomontage Document as a Smart Object.

In Photoshop, resize, rotate and transform as necessary to integrate the vector design.
