How to Scale a Sewing Pattern
Sewing patterns are essential tools for creating custom garments and accessories. However, one of the most common challenges faced by sewists is knowing how to scale a sewing pattern to fit their unique body measurements. Scaling a pattern involves adjusting its size to match the desired body proportions, ensuring a comfortable and stylish fit. In this article, we will discuss the step-by-step process of how to scale a sewing pattern, from selecting the right pattern to making the necessary adjustments.
Selecting the Right Pattern
Before you begin scaling a sewing pattern, it’s essential to choose the right pattern that closely matches your body measurements. Look for patterns that offer a range of sizes or have the option to add or subtract width. This will make the scaling process more straightforward and accurate.
Understanding Pattern Notations
Before you start scaling, familiarize yourself with the pattern’s notations. This includes understanding the size chart, grainline, and how to interpret the pattern pieces. Knowing these elements will help you make informed decisions during the scaling process.
Calculating the Scale Factor
To scale a pattern, you need to determine the scale factor, which is the percentage by which you want to increase or decrease the pattern’s size. To calculate the scale factor, subtract the desired size from the original size, divide the result by the original size, and then multiply by 100. For example, if you want to increase the size from a 12 to a 14, the calculation would be (14 – 12) / 12 100 = 16.67%. This means you need to increase the pattern by 16.67%.
Adjusting the Pattern Pieces
Once you have determined the scale factor, it’s time to adjust the pattern pieces. Start by drawing a line parallel to the grainline on each pattern piece. Measure the desired width (based on your scale factor) and mark it on the new line. Connect the marks to create the new pattern piece.
Redrawing the Pattern Pieces
After adjusting the pattern pieces, redraw them on a new sheet of paper. This will ensure that the pattern pieces are clean and accurate. Pay attention to the grainline and make sure it is parallel to the selvage of the fabric.
Checking the Fit
Before cutting out the fabric, it’s essential to check the fit of the scaled pattern. Use muslin or a lightweight fabric to create a toile (a practice garment). Try on the toile and make any necessary adjustments to the pattern pieces before cutting out the final fabric.
Conclusion
Scaling a sewing pattern may seem daunting at first, but with a bit of practice and patience, you can create custom garments that fit perfectly. By following these steps, you’ll be able to adjust your patterns to match your unique body measurements and create a wardrobe that reflects your personal style. Happy sewing!
