"Kushee" is by Verena Bossert and her lovely pattern is found HERE at Pattern-Collections.com. This is a fun and easy pattern to draw. I embellished mine with a dot of metallic gel pen in the center of each square.

If you compare the example image on the step-out with the actual steps, you will see that one step is missing. In between steps one and two, you should draw pen lines in each box that go from corner to corner by tracing over the pencil grid lines. Otherwise you will end up with a gap between the radiating lines that are drawn in steps 2-5 and the arcs that are drawn in step six. These gaps are there in step six of the step-out but there are no gaps in the sample image. If you leave those gaps the outcome will look different than the sample.
