I noticed right away that this simple five patch block called Flying Square looked like a plaid or tartan design, and so, I created the two sample quilt layouts shown below with that thought in mind, featuring the colours in one of the many Johnson clan tartans.

The quilt layout illustrated on the left sets the blocks side by side. By separating the blocks with sashing strips of a variety of colour combinations, I think I achieved the look of the tartan.

The quilt layout featured on the right sets the quilt blocks on point for a different look. The sashing strips use different colours in opposite directions to add that little bit of an accent that you would see in a plaid fabric.
