Two parallel lines that show where to shorten or lengthen a pattern piece are called?

• A. Adjustment lines
• B. Grain lines
• C. Seam lines
• D. Cutting lines

Answer: (A)

These two parallel lines are adjustment lines. They’re placed across a pattern piece to indicate where you can change the length of the piece without altering its shape or width. If you need to shorten, you cut between the lines and overlap the sections to reduce length, then tape in place. If you need to lengthen, you spread the pieces apart between the lines and add paper to fill the gap, then tape. This method lets you adjust the length to fit you precisely while keeping the rest of the pattern intact. The other lines—grain lines, seam lines, and cutting lines—serve different purposes (fabric direction, where pieces join, and where to cut), so using the adjustment lines correctly is the way to modify length.
