Shrinking Sewing Patterns: A Beginner's Guide

Hey there, sewing enthusiasts! Ever find a pattern you absolutely adore, but it's just a tad too big? Or maybe you've lost some weight (congrats, by the way!) and now your favorite patterns are swimming on you? Don't worry, we've all been there! Making a sewing pattern smaller might seem daunting at first, but trust me, it's totally doable. It's like tailoring, but with paper! In this guide, we'll dive into the essential steps and techniques you can use to shrink those patterns down to the perfect size. We'll cover everything from simple adjustments to more complex alterations, so you can confidently tackle any pattern shrinking project. Let's get started, shall we?

Understanding Pattern Sizing and Your Measurements

Before you even think about grabbing your scissors, you need to understand pattern sizing. Pattern sizing often differs from ready-to-wear clothing sizes, so don't be surprised if you're a different size on a pattern than you are in the store. This is because pattern companies use standardized measurements, but these measurements can vary between brands. The first step is taking accurate measurements. You'll need a flexible measuring tape and a helper can be useful, though not essential. Measure your bust, waist, and hips. It's also a good idea to measure your shoulder width, and inseam. Always measure over the clothes you'll be wearing under the final product. Write these down. Compare these to the pattern's size chart, which you'll find on the pattern envelope or instructions. Choose the size that most closely matches your measurements. Sometimes, your measurements will put you in different sizes for different parts of the pattern. For instance, you might need a size 12 for your bust but a size 10 for your waist. In such cases, you'll need to blend between sizes. This involves drawing a smooth line to connect the different sizes on the pattern pieces. It might sound complicated, but we'll cover it further down. It's essential to understand that patterns are often designed with a certain amount of ease, which means extra room for movement and comfort. The amount of ease varies depending on the garment and the pattern designer. Before you make any adjustments to a pattern, it's important to understand the concept of ease. Now, armed with your measurements and a basic understanding of pattern sizing, you're ready to start shrinking! This part is crucial for success, so don't skip it, guys!

Simple Adjustments: Taking In Seams

Okay, so you've got your measurements and chosen your pattern size. Now, let's start with some easy adjustments. Taking in seams is one of the simplest ways to make a pattern smaller, especially if you only need to reduce the size by a small amount. This method involves reducing the seam allowance. This approach works best when you want to make small adjustments, such as taking in a dress at the waist or hips. Remember to use a smaller seam allowance throughout, otherwise it will be unbalanced and the garment will not sit right. Here's how to do it:

  1. Identify the Seams: Look at your pattern pieces and identify the seams that you want to adjust. Common seams for adjustment include side seams, princess seams, and back seams. You can usually find the seam allowance marked on the pattern pieces. It is the space between the cutting line and the stitching line.
  2. Reduce the Seam Allowance: Determine how much you want to reduce the pattern. Divide the total amount you want to reduce by the number of seams you’re adjusting. For example, if you want to reduce the waist by 2 inches and you have two side seams, you will reduce each seam allowance by 1 inch. Use a ruler and pencil to redraw the seam allowance, making it narrower. For instance, if the original seam allowance is 5/8 inch, you might reduce it to 1/2 inch or 3/8 inch. Remember, you can always take more off, but you can't add it back! It's better to start small and make adjustments as needed.
  3. Blend the Lines: Use a ruler or French curve to smooth out the new seam lines, ensuring they blend smoothly into the original pattern. This is crucial for a professional-looking finish. You want a gradual and even change.
  4. Cut and Sew: Cut out your pattern pieces along the new seam lines. When sewing the garment, sew along the new, narrower seam allowances. Make sure the lines are smooth and that you are not creating a sudden angle in the pattern that will be visible in the finished product. Sew the seams and try on the garment. You may need to make additional adjustments. Taking in seams is a great starting point, especially for slight adjustments. This method is suitable for areas where you want a more fitted look, like the waist or hips. But what if you need to take off more? Let's move onto more complex methods!

Advanced Techniques: Full Bust Adjustment (FBA) and Full Seat Adjustment (FSA)

Now, let's get into some more advanced techniques for significantly altering patterns. These adjustments are particularly helpful when you have a significant difference in your measurements compared to the standard pattern size. We are going to dive into the Full Bust Adjustment (FBA) and the Full Seat Adjustment (FSA). FBA is used when your bust measurement is larger than the pattern size, while FSA is used when your hip measurement is larger. These techniques involve strategically adding or subtracting fabric from the pattern to accommodate these differences. These methods can also be used if the person is very flat chested, in the same way, but it would be a Small Bust Adjustment (SBA). FSA can be done the opposite as well, as a Small Seat Adjustment (SSA). Let's go through the steps for both.

Full Bust Adjustment (FBA):

  1. Find the Apex: Locate the apex, or bust point, on the pattern piece (usually the front bodice). This is the point where the bust is most prominent. This is usually marked on the pattern.
  2. Draw the Lines: Draw a horizontal line from the apex to the side seam. Then, draw a vertical line from the apex to the bottom hem. Finally, draw a line from the apex to the shoulder seam. Cut along these lines, but leave a small hinge at the apex so the pattern stays together.
  3. Spread the Pattern: Place a piece of paper under the pattern. Spread the pattern pieces apart, creating a gap along the lines you cut. The amount you spread the pattern depends on the difference between your bust measurement and the pattern's bust measurement. Use your measurements from the first step in this guide, to determine how much you need to spread the pattern pieces.
  4. Tape and True: Tape the pattern pieces to the paper, creating a smooth line. The amount you spread the pattern pieces apart will determine how much bigger the pattern becomes. Remember, you are adding the pattern to increase the bust size.
  5. Adjust Darts: Redraw the darts to accommodate the added fullness. This may involve lengthening or widening the darts.

Full Seat Adjustment (FSA):

  1. Find the Apex: Locate the apex, or fullest part of the hip, on the pattern piece (usually the back). This is the point where the seat is most prominent. This is usually marked on the pattern.
  2. Draw the Lines: Draw a horizontal line from the apex to the side seam. Then, draw a vertical line from the apex to the bottom hem. Cut along these lines, but leave a small hinge at the apex so the pattern stays together.
  3. Spread the Pattern: Place a piece of paper under the pattern. Spread the pattern pieces apart, creating a gap along the lines you cut. The amount you spread the pattern depends on the difference between your hip measurement and the pattern's hip measurement. Use your measurements from the first step in this guide, to determine how much you need to spread the pattern pieces.
  4. Tape and True: Tape the pattern pieces to the paper, creating a smooth line. The amount you spread the pattern pieces apart will determine how much bigger the pattern becomes. Remember, you are adding the pattern to increase the hip size.
  5. Adjust Darts: Redraw the darts to accommodate the added fullness. This may involve lengthening or widening the darts.

These adjustments, while more complex, are essential for achieving a good fit if your body shape differs significantly from the standard pattern measurements. Don't be afraid to experiment and practice. There are plenty of online resources and tutorials that can guide you through these techniques step-by-step. Remember, practice makes perfect!

Adjusting for Different Fabrics and Designs

Fabric choice and garment design can also influence how you approach pattern adjustments. For instance, if you're working with a stretchy knit fabric, you might not need to make as many adjustments as you would with a woven fabric, since knits have more give. The style of the garment matters too. A loose, flowing dress will require fewer adjustments than a fitted sheath dress. Remember to always consider the fabric's properties and the garment's design when making adjustments. Also, if your design involves multiple pattern pieces, make sure to adjust all the relevant pieces to maintain the garment's proportions. For example, if you're adjusting the front bodice for an FBA, you may also need to adjust the side panel or back bodice to maintain the balance of the garment. It's often helpful to make a muslin – a test garment made from inexpensive fabric – to check your adjustments before cutting into your final fabric. A muslin will allow you to fine-tune your fit and make any final adjustments before you commit to your main project. This is especially important when using expensive or delicate fabrics.

Essential Tools for Pattern Adjustments

Having the right tools can make the pattern adjustment process much easier and more enjoyable. Here's a list of essential tools:

  • Measuring tape: For accurate measurements. It is one of the most important tools.
  • Ruler and/or French curve: For redrawing and smoothing seam lines. The ruler is used for straight lines, while the French curve is for curved lines.
  • Pencil and Eraser: For marking, drawing, and correcting lines on your pattern. You may want to start with a pencil because it is easy to erase if you made a mistake.
  • Scissors or Rotary cutter: For cutting the pattern pieces. Using a rotary cutter with a cutting mat can be helpful for precision.
  • Tape: For taping pattern pieces together. Masking tape or painter's tape works well.
  • Tracing paper: For tracing the pattern to make copies or for making adjustments without altering the original pattern. This is a very useful tool, because you can make copies and test your different patterns to make sure you have the perfect design.
  • Pattern weights: To hold the pattern in place while cutting. These can be anything from actual pattern weights to washers or even small rocks.
  • Pins: For pinning the pattern pieces to the fabric. You can use this instead of weights.

Practice, Practice, Practice!

Making sewing patterns smaller is a skill that improves with practice. Don't get discouraged if your first attempt isn't perfect. Each project is a learning experience.
