Center front (CF) and center back (CB) are imaginary plum lines used in apparel pattern making. Understanding plum lines and horizontal points of measure lines (POM) are essential in creating a balanced and well-fitting garment.
Understanding Plum Lines
Plum lines are vertical reference lines that help in aligning the pattern pieces accurately. The CF and CB lines serve as the basis for symmetry and balance in garment construction. They are crucial for:
Establishing the overall silhouette of the garment.
Ensuring proper alignment of pattern pieces during cutting and sewing.
Facilitating accurate fitting and adjustments.

Horizontal Points of Measure Lines (POM)
Horizontal POM lines are used to measure the width and depth of various garment parts. They provide reference points for:
Determining bust, waist, and hip measurements.
Establishing the placement of design elements such as darts, seams, and pockets.
Ensuring that the garment maintains its intended proportions and fit.
Importance of Balance in Garment Construction
Achieving balance in garment construction involves careful consideration of both vertical and horizontal measurements. This ensures:
Comfort and ease of movement for the wearer.
Aesthetic appeal and visual symmetry.
Functionality in design, allowing for proper drape and structure.
In summary, a solid understanding of CF, CB, plum lines, and POM lines is fundamental in the pattern-making process, leading to the creation of garments that fit well and look great.
