I am attaching a sketch (and I am not a good sketcher) of my quilt I am making and would like for someone to figure the yardage I need for the borders and center block. The outside 8" border, the 4"border around center block, 2" border around center block and the center block. Have I confused you yet? I have figured it but not sure I am correct since I haven't made a quilt in several years where I had to figure for borders. Thanks for your help.
