Body Measurement and Basic Pattern Drafting
Body measurement refers to the process of taking precise measurements of various parts of the human body, typically for the purpose of tailoring or fitting clothing or assessing body composition. Body measurements can include measurements of height, weight, chest, waist, hips, shoulders, arms, legs, and other body parts.
The accuracy of body measurements is important in many fields, such as fashion design, sports, fitness, health care, and anthropology. In fashion design, accurate body measurements are essential for creating well-fitting clothing. In sports and fitness, body measurements can help track changes in body composition and guide exercise and nutrition plans. In health care, body measurements can be used to diagnose and monitor medical conditions, such as obesity or malnutrition. In anthropology, body measurements can provide information about human physical variation and evolution.
Body measurements are typically taken using a tape measure or other measuring tools. In order to get accurate measurements, it is important to follow standardized measurement protocols and take measurements at consistent anatomical landmarks. Body measurements can be taken by oneself or by another person, depending on the body part being measured and the level of precision required.
Basic pattern drafting is the process of creating a pattern that can be used as a blueprint for creating a piece of clothing. It involves taking precise measurements of a person’s body and using those measurements to create a custom-fit pattern.
The basic pattern drafting process involves several steps:
- Taking accurate measurements: The first step in pattern drafting is taking precise measurements of the body. This includes measurements of the bust, waist, hips, and other key areas.
- Drafting the pattern: Once the measurements have been taken, the pattern is drafted onto paper or pattern drafting software. This involves drawing lines and curves based on the measurements taken, and using basic pattern blocks as a starting point.
- Testing the pattern: Once the pattern has been drafted, it’s important to test it by making a muslin or toile (a test garment made from cheap fabric) to check the fit and make any necessary adjustments.
- Refining the pattern: After testing the pattern and making any necessary adjustments, the final pattern is refined and perfected.
Once the pattern has been created, it can be used to create a finished garment by cutting the fabric according to the pattern pieces and sewing them together. With practice, pattern drafting can be used to create a wide range of garments, from simple tops and dresses to more complex designs.
Pattern Markings and Symbols
Pattern markings and symbols are used in sewing patterns to communicate important information to the sewer about how to lay out and cut fabric pieces, where to place pattern pieces on the fabric, and how to assemble the garment. Here are some common pattern markings and symbols and their explanations:
- Grainline: A straight line with arrows at each end indicating the direction of the grain of the fabric. The grainline should be placed parallel to the selvage edge of the fabric when laying out the pattern pieces.
- Notches: Triangular or diamond-shaped markings placed along the edges of pattern pieces. Notches help the sewer match up corresponding pieces and ensure that the garment is assembled correctly.
- Dots: Small circles that indicate where to place pattern pieces on the fabric. Dots are often used in conjunction with notches to ensure that pieces are aligned properly.
- Cutting lines: Solid lines that indicate where to cut the fabric. Cutting lines may be different from the seam lines, which indicate where to sew the pieces together.
- Seam allowances: The area between the cutting line and the seam line where the fabric will be sewn together. Seam allowances are typically 5/8 inch, but may vary depending on the pattern.
- Stitching lines: Dashed or dotted lines that indicate where to sew the fabric pieces together.
- Fold lines: A solid line that indicates where the fabric should be folded. Fold lines are often used for pattern pieces that need to be cut on the fold, such as the front or back of a skirt.
- Placement lines: A dashed line that indicates where to place a design element, such as a pocket or appliqué.
- Grainline arrow: An arrow that indicates the direction of the grainline. Grainline arrows are used for pattern pieces that need to be cut on the bias, such as a bias-cut skirt.
- Buttonhole placement markings: Small markings that indicate where to place buttonholes on the finished garment.
Understanding pattern markings and symbols are essential to successfully sewing a garment from a pattern. Sewers should carefully read and follow the instructions provided with the pattern to ensure that they correctly interpret and use all pattern markings and symbols.
