it is a simple 4 unit square. but each unit is half one color and half another.they look to be a 4 inch finished unit, with it having two colors. To make the 4inch unit u will need two pieces which will be the same size. to get these you cut 4 1/2 inch blocks , then you cut these in half. you do this with both of the colors u are using. so if u cut one square of each color, and cut both in half , u will have 4 pieces. then u sew the 2 colors together and u will have 2 4inch units. You make 4 of these units for each 8 inch block. then lay them out to get the pattern . Does this make sense?
