The first picture is of the block assembly instructions for the Brothers and Sisters quilt.
The book says that if I sew together four 9" blocks it will create an 18 1/2" square block. Using a 1/4" seam allowance, it seems to me that sewing four 9" blocks together would create a 17 1/2" square block.
Is the pattern wrong or is there something I am not understanding?
Next the book says that sewing nine 6" blocks together will create an 18 1/2" square block. I would think it would make a 17" block.
The second picture shows the quilt blocks sewn together. How do I make the 6" and 9" blocks into squares that are the same size?
I am so confused.
