How to Create Sewing Patterns from Existing Clothes

Creating sewing patterns from existing clothes is a valuable skill for both beginners and experienced seamstresses. It allows you to replicate and customize your favorite garments, create new designs, or recycle old clothes into something new. Whether you're looking to duplicate a well-loved item in your wardrobe or repurpose materials, transforming your clothes into patterns opens up countless possibilities.

This guide will take you through the process of creating sewing patterns from existing clothes, covering everything from preparing the garment for pattern-making to drafting, cutting, and stitching your custom pattern.

Preparing the Garment for Pattern-Making

Before you can start drafting your sewing pattern, it is essential to prepare the garment properly. The preparation phase ensures that you can trace accurate dimensions and replicate the garment with precision.

Selecting the Garment

Choose a garment that is well-constructed and fits you well. It's best to select something you wear frequently and feel comfortable in. Garments that are too worn out or stretched out may not provide accurate results, as their shapes and sizes could have changed over time.

Cleaning the Garment

Wash and iron the garment before beginning the pattern-making process. This helps to ensure that the fabric is clean, free of wrinkles, and pre-shrunk, which is important for both accurate measurements and fabric preparation.

Analyzing the Garment's Structure

Examine the garment carefully to understand its design features. Look at the construction elements like seams, darts, pleats, tucks, or finishes that may affect how the pattern will be drawn. Pay attention to details such as zippers, buttons, or pockets, as they will need to be replicated in the pattern if you wish to include them in your design.

Materials Needed for Pattern-Making

Before you start drafting your pattern, gather the following materials:

• The garment to copy: This is your template, and it will be used as a guide.
• Pattern paper: This is used to trace your pattern. You can find rolls or sheets of pattern paper, or you can use alternatives like butcher paper or tracing paper.
• Measuring tools: A tape measure, ruler, and french curve or hip curve will help you capture accurate measurements and smooth curves.
• Pins: Used to hold the garment in place while tracing.
• Scissors: To cut the pattern paper.
• Chalk or fabric marker: For marking the fabric or pattern paper.
• Tracing wheel: Used to transfer markings from the garment to the paper.
• Weights or pins: To hold the fabric in place when copying its structure.

Creating the Pattern from the Garment

Now comes the fun part---transferring the garment's design onto pattern paper! This involves tracing out the pieces and making any necessary adjustments to ensure a perfect fit and construction.

Step 1: Lay the Garment Flat

Place the garment flat on a clean, flat surface, such as a large table or cutting mat. Smooth out any wrinkles to ensure the fabric lays flat. If necessary, fold or adjust the garment so that you can easily trace around the edges.

Step 2: Trace the Main Pieces

Start by tracing the largest pieces of the garment, such as the front and back bodice, skirt, sleeves, etc. Pin the garment in place on the pattern paper to prevent it from shifting. Use a pencil or fabric chalk to trace along the edges of the garment, making sure to follow all the curves and seams.

Tips:

• Trace both the outer and inner edges of the garment to ensure you have accurate seam allowances.
• Add extra space to the pattern for seam allowances (usually 1/4 to 1/2 inch) unless you plan to add the seam allowances during cutting.
• For garments with darts or pleats, mark these as well, as they will need to be transferred to the pattern.

Step 3: Mark Key Details

Once you've traced the main shapes, mark key details such as darts, pleats, button placements, and zipper lines. You can use a tracing wheel or fabric chalk to transfer markings from the garment to the pattern paper. If your garment has a waistband, pockets, or collar, these must also be traced and included in the pattern.

Step 4: Add Notches and Cutting Lines

Notches and cutting lines help ensure that the different pieces of the pattern fit together correctly. These small markings are added to the edges of the pattern to indicate where certain seams meet. You can mark these with a small notch or a line on the pattern paper.

Step 5: Create the Sleeves and Other Smaller Pieces

For sleeves, cuffs, collars, and other smaller components, lay the garment flat and trace these parts individually. If the sleeves are set-in (not raglan), make sure to measure the armhole to ensure the sleeve will fit properly.

If the garment has a lining or facing, don't forget to trace those pieces as well. These will also need seam allowances added to ensure they fit properly.

Step 6: Make Adjustments for Fit

Once you've traced the garment, it's important to make adjustments for fit. Some garments may be too tight, too loose, or may not sit well on your body in specific areas. Modify the pattern to match your desired fit.

• Add ease: Ease is extra room added to a pattern to ensure comfort and movement. If you want a looser fit, add ease to the side seams or across the bust and waist.
• Correct any design flaws: If you notice areas where the garment doesn't fit well, like too much fabric around the waist or not enough space around the bust, adjust your pattern accordingly.

Step 7: Mark Pattern Pieces

Label each pattern piece clearly with its name (e.g., "Front Bodice," "Back Skirt"), and add any important details such as the grainline, center front, or center back. You may also want to add notations about the fabric type and cutting instructions.

Cutting Out the Pattern

Once you have completed your pattern, it's time to cut out the pieces. Be sure to cut carefully and precisely, as any mistakes will carry over into your finished garment.

Step 1: Pin the Pattern to Fabric

Lay the pattern pieces on fabric, following the grainline and fabric's natural stretch (if applicable). Use pins or weights to secure the pattern in place. Be sure to leave room for seam allowances and any extra markings.

Step 2: Cut Out the Fabric Pieces

Using fabric scissors, carefully cut around the pattern pieces. Make sure to follow the edges precisely to ensure the pieces fit together when assembled.

Step 3: Mark Key Points on the Fabric

Before removing the pattern, mark key points like darts, notches, or pocket placements directly on the fabric with fabric chalk or a washable marker.

Assembling the Garment

Now that you have your pattern pieces cut out and ready, the final step is to assemble the garment.

Step 1: Sew the Pieces Together

Begin by stitching the major seams, starting with the shoulder seams, side seams, and sleeve seams. If your pattern has any darts or pleats, sew these first to ensure the garment takes its shape.

Step 2: Try the Garment on

Before finishing the hem or attaching any additional components (like zippers or buttons), try the garment on to check the fit. Make any necessary adjustments, such as shortening or lengthening the hem, taking in or letting out seams, or adding extra ease in certain areas.

Step 3: Final Touches

Once you're satisfied with the fit, finish the garment by adding any final details like hems, zippers, buttons, or decorative elements. Ensure all raw edges are properly finished to avoid fraying.

Tips for Success

• Start Simple: If you're a beginner, start with a simple garment, such as a basic t-shirt or skirt, to practice the process of pattern-making and sewing.
• Use Existing Patterns: If you're unsure about the fit or design, use an existing pattern as a guide to help you with the construction process.
• Adjustments are Key: Don't be afraid to make adjustments to your pattern to ensure the best fit. Patterns can often be tweaked, especially when copying a garment that is made of stretch fabrics or features unique design elements.
• Be Patient: Creating a pattern from an existing garment takes time, but the results are worth it. Take your time to measure carefully and make precise markings to ensure a professional result.

Conclusion

Creating sewing patterns from existing clothes is a valuable skill that opens up a world of creative possibilities. Whether you're replicating a favorite garment, designing your own clothes, or upcycling old items, the ability to turn your clothes into patterns is an essential skill for any sewist.

With the right tools, techniques, and a bit of patience, you can create professional-quality patterns that fit your style, taste, and body perfectly.
