Making the boat neck dress pattern

1. Make and cut the boat neck dress pattern

Start with two pieces of fabric measuring 90 x92 centimeters (35.4 x 36.2 inches) each. Put one piece on top of the other with the right sides facing down. You will be cutting both layers at the same time.


Fold the fabric widthwise so you have 92 centimeters (36.2 inches) along the folded edge and 45 centimeters (17.7 inches) along the short edge.

Draw a line from that 22-centimeter (8.66-inch) mark, down 15 centimeters (5.9 inches), and then go across to the right-hand edge so you have a 15 x 70-centimeter (5.9 x 27.55-inch) rectangle in the upper right corner of your fabric.
