I started with one 6″ border then added 2 more 6″ borders, then 1 – 7, 8″, 9″,10″,11″,12″ & 13″ border and a 3/8″ one as binding. After playing with different border designs I thought the center looked like a window, so I added one 6″ center block and used shades of black and dark lime green for coloring.
