How to Upsize a Sewing Pattern
Sewing patterns are a fundamental tool for any fashion enthusiast or professional seamstress. However, it’s not uncommon to find that the size of the pattern doesn’t quite match your body measurements. Whether you’re looking to create a garment that fits perfectly or you’ve found a pattern that’s slightly too small, up-sizing a sewing pattern is a valuable skill to have. In this article, we will guide you through the process of how to upsize a sewing pattern, ensuring that your next sewing project is tailored to fit you perfectly.
Understanding the Pattern
Before you begin the up-sizing process, it’s essential to understand the sewing pattern you’re working with. Most patterns include a size chart that lists the finished garment measurements. Compare these measurements to your own body measurements to determine which size is closest to your fit. Keep in mind that you may need to upsize if your body measurements are significantly larger than the pattern size.
Calculating the Increase
To upsize a sewing pattern, you’ll need to calculate the increase in size. Start by determining the difference between your body measurements and the pattern size. For example, if the pattern size is 8 and your bust measurement is 42 inches, you would need to increase the pattern by 4 inches. Divide this difference by the number of pattern pieces to determine the increase per piece.
Adjusting the Pattern Pieces
Once you’ve calculated the increase, it’s time to adjust the pattern pieces. Begin by drawing a new line on each pattern piece where the increase needs to be made. This line should be parallel to the original cutting line. Measure the increase from the original cutting line to the new line and mark it on the pattern piece. Repeat this process for all pattern pieces that require adjustment.
Adding Ease
Adding ease is crucial when up-sizing a sewing pattern. Ease refers to the extra room added to the pattern to ensure the garment fits comfortably. To add ease, draw a line from the original cutting line to the new line, creating a triangle shape. The height of the triangle will depend on the amount of ease you need. For most garments, a 1/2-inch to 1-inch ease is sufficient. Once you’ve drawn the triangle, cut along the new line and the original cutting line to separate the pattern piece.
Joining the Pieces
After adjusting the pattern pieces, it’s time to join them back together. Align the pieces along the original cutting line and pin them in place. Make sure that the edges are even and the notches match. Once the pieces are aligned, you can cut out the pattern pieces from your fabric.
Conclusion
Upsizing a sewing pattern is a straightforward process that can be accomplished with a few simple steps. By understanding the pattern, calculating the increase, adjusting the pattern pieces, adding ease, and joining the pieces, you can create a garment that fits perfectly to your body measurements. With practice, you’ll become more comfortable with this technique and be able to customize any pattern to suit your unique style and fit. Happy sewing!
