Step two: From each of six (6) different print fabrics cut four (4) 412in 60-degree triangles.

Step three: From the cushion back fabric cut two (2) 2312in x 1612in rectangles.

Step four: From the binding fabric cut three (3) 212in x WOF strips.

Making the large cushion

Step five: Arrange the white and print fabric triangles into six rows of eleven triangles each, experimenting with different print placements and rotating alternate triangles by 180 degrees so that the triangles tessellate.
