How to Enlarge Patterns for Sewing- Step-by-Step Guide to Perfectly Scaling Your Sewing Projects

How to Enlarge Patterns for Sewing

When it comes to sewing, having the right size pattern is crucial for a successful project. However, sometimes the patterns we have may not fit our desired size or body measurements. In such cases, knowing how to enlarge patterns for sewing becomes essential. This article will guide you through the process of enlarging patterns, ensuring that your sewing projects turn out perfect every time.

Understanding Pattern Enlargement

Pattern enlargement is the process of making a pattern larger or smaller to fit the desired size. This is commonly done using a photocopier, a pattern enlarger, or by hand. Before you begin, it’s important to understand that enlarging a pattern will also increase the seam allowances, so you’ll need to adjust them accordingly.

Using a Photocopier to Enlarge Patterns

One of the most convenient methods for enlarging patterns is using a photocopier. Here’s how to do it:

1. Trace the pattern onto a transparent sheet of plastic or a tracing paper.
2. Place the traced pattern on the photocopier’s glass or on a flatbed scanner.
3. Adjust the settings on the photocopier to the desired percentage of enlargement.
4. Print the pattern onto paper.
5. Cut out the enlarged pattern pieces and reassemble them.

Using a Pattern Enlarger

Another option for enlarging patterns is using a pattern enlarger. These devices are specifically designed for this purpose and offer a more accurate and precise enlargement. Here’s how to use a pattern enlarger:

1. Place the pattern onto the enlarger’s glass.
2. Adjust the focus and magnification to the desired size.
3. Trace the pattern onto paper using the enlarger’s pen or pencil.
4. Cut out the pattern pieces and reassemble them.

Enlarging Patterns by Hand

If you prefer a more hands-on approach, you can enlarge patterns by hand. Here’s how to do it:

1. Trace the pattern onto a transparent sheet of plastic or a tracing paper.
2. Place the traced pattern onto a flat surface.
3. Draw lines connecting the points of the pattern.
4. Measure the desired size and mark the new points on the lines.
5. Extend the lines to the new points, creating the enlarged pattern.
6. Cut out the pattern pieces and reassemble them.

Adjusting Seam Allowances

After enlarging the pattern, you’ll need to adjust the seam allowances. Seam allowances are the extra fabric added to the edges of the pattern pieces to allow for stitching and finishing. To adjust the seam allowances:

1. Measure the original seam allowances on the pattern.
2. Multiply the seam allowances by the percentage of enlargement.
3. Add the new seam allowances to the pattern pieces.

Conclusion

Enlarging patterns for sewing is a valuable skill that can help you achieve the perfect fit for your projects. Whether you choose to use a photocopier, a pattern enlarger, or hand-trace the pattern, following these steps will ensure that your sewing patterns are always the right size. Happy sewing!
