The quilt pattern calls for taking a 6 7/8 inch square and cutting it diagonally. then pair it up with the other color 6 7/8 inch square and cut diagonally. Then sew together to make a square. Does it come out exactly the same if I put the two squares together, draw a line diagonally down the center and sew 1/4 inch away from the line on both sides. Then, cut down the pencil line? Expensive fabric. Just want to make sure I am correct before I sew and cut.
