How to Alter a Sewing Pattern Size: A Step-by-Step Guide
Embarking on a sewing project is an exciting endeavor, but it can be daunting when the pattern size doesn’t quite fit. Whether you’re looking to downsize for a sleeker silhouette or upsize for a more comfortable fit, altering a sewing pattern size is a skill every sewer should master. In this article, we’ll walk you through the process of how to alter a sewing pattern size, ensuring your finished garment is both stylish and tailored to your body measurements.
Step 1: Measure Yourself
Before you start making any adjustments to your pattern, it’s crucial to take accurate measurements of your body. Use a soft measuring tape and measure key areas such as bust, waist, hip, shoulder, and inseam. Compare these measurements to the size chart provided with your pattern to determine the initial size you’ll need to work with.
Step 2: Choose the Pattern to Alter
Select the pattern you wish to alter. It’s important to have a clear understanding of the pattern pieces and their corresponding body parts. Familiarize yourself with the symbols and notations on the pattern, as these will guide you through the alteration process.
Step 3: Determine the Pattern Size
Identify the size of the pattern that matches your measurements the closest. This will serve as the starting point for your alterations. Keep in mind that patterns are designed to have a certain amount of ease, so you may not need to make significant changes if your measurements are very close to the pattern size.
Step 4: Draw a New Grading Line
If you need to adjust the size of the pattern, start by drawing a new grading line. This line will connect the various pattern pieces and indicate where the size change will occur. To do this, measure the distance from the original size line to the new size line, and draw a straight line connecting the corresponding points on each pattern piece.
Step 5: Adjust the Pattern Pieces
Now, it’s time to adjust the pattern pieces. Depending on whether you’re adding or subtracting length, width, or both, follow these steps:
– To add length: Extend the pattern piece along the grading line and redraw the edge to the desired length.
– To subtract length: Shorten the pattern piece along the grading line and redraw the edge to the desired length.
– To add width: Draw a straight line from the original size line to the new size line, and redraw the edge to the desired width.
– To subtract width: Narrow the pattern piece along the grading line and redraw the edge to the desired width.
Step 6: Redraw Seam Allowances
After adjusting the pattern pieces, redraw the seam allowances to ensure they are consistent with the new size. This will help prevent any unwanted bulk or gathers in the finished garment.
Step 7: Test the Pattern
Before cutting into your fabric, test the pattern on paper or a muslin to ensure that the alterations have been made correctly. This will help you identify any potential fitting issues before you invest time and fabric into the project.
Step 8: Cut and Sew
Once you’re confident in the pattern’s fit, cut your fabric according to the adjusted pattern pieces. Proceed with the construction of your garment, following the pattern instructions.
By following these steps, you’ll be well on your way to altering a sewing pattern size with confidence. Remember, practice makes perfect, so don’t be afraid to experiment with different alterations until you achieve the perfect fit for your sewing projects. Happy sewing!
