The correct answer is that the facing strip used to finish a round neckline is cut at a 45° angle to the selvedge. This technique is commonly referred to as cutting on the bias.
This method is chosen because:
The correct answer is (3) At 45° angle to selvedge.
When finishing a round neckline, the facing strip (used to finish the neckline) is typically cut at a 45° angle to the selvedge. This angle allows the fabric to have some stretch and flexibility, which helps the neckline to sit smoothly and maintain its shape without puckering. Cutting it at a 45° angle allows the fabric to conform more easily to the curve of the neckline.
Let’s review the other options:
(1) Parallel to selvedge: Cutting parallel to the selvedge would make the fabric less flexible and could cause the neckline to become stiff or not curve well.
(2) Perpendicular to selvedge: Cutting perpendicular to the selvedge could make the fabric too rigid and not allow the neckline to form properly.
(4) At 90° angle to selvedge: Cutting at a 90° angle is essentially perpendicular, which would have similar issues as mentioned in option (2), leading to less flexibility for the neckline.
Thus, the correct answer is (3) At 45° angle to selvedge, as this provides the ideal balance of stretch and stability for finishing a round neckline.
