For a continuous placket, the pattern piece required is typically twice the length of the finished placket, plus an additional 1 inch extra for seam allowances and turning the fabric. This ensures there is enough material for folding, stitching, and finishing the placket properly.
Let's review the options:
(1) Same as the width of the finished placket + 1 inch extra: This is incorrect. The length of the pattern piece is not determined by the width of the finished placket; it is based on the length of the placket.
(2) Twice the length of the finished placket + 1 inch extra: This is correct. The pattern piece required for a continuous placket should be twice the length of the finished placket plus 1 inch extra for seam allowances.
(3) Three times the length of the finished placket + 1 inch extra: This is incorrect. You only need to double the length of the finished placket, not triple it.
(4) Same as the length of the finished placket + 1 inch extra: This is incorrect. The pattern piece needs to be twice the length of the finished placket to allow for the necessary folds.
Thus, the correct answer is (2) Twice the length of the finished placket + 1 inch extra.
A continuous placket requires a pattern piece that is double the length of the placket itself, with an additional inch to account for seam allowance. This ensures that the fabric can overlap adequately and provides enough material for secure finishing.
