Draw the grid on the reverse of the fabric and mark the
slanting lines. Leave a border of 3cm all around.
Do the smocking using matching thread. The fabric takes the shape of rhombus after smocking.
Place a square cardboard of measurement 42 cm in the smocked fabric as shown. I have used quilting rulers.
Draw line all around Fix the position of the pleats using 3m tape.
