In this guide, I demonstrate the process of transforming an existing t-shirt into a pattern by laying it flat, pinning it to a paper, and tracing the outline.

I provide step-by-step instructions on how to properly align the t-shirt pieces, mark the necessary points, and transfer the front, back, and sleeve sections onto the paper to create a reusable pattern.

Steps Involved (Instructional Guide):

1. Press the t-shirt to ensure it is flat and straight.
2. Lay half of the t-shirt on a paper or mat, pinning at the underarm, neck, shoulder, and armhole points to keep it in place.
3. Mark the center front, center back, and other key points with chalk or a marker.
4. Draw lines around the neckline, armholes, and side seams, following the t-shirt’s outline.
5. Repeat the process for the back piece of the t-shirt.
6. Align the front and back pieces, matching the shoulder seams, center front, and center back.
7. Trace the side seams, adjusting for any length differences between the front and back.
8. For the sleeve, fold the paper and place the shoulder point of the sleeve on the fold.
9. Straighten and pin the sleeve, ensuring it lays flat.
10. Trace the sleeve outline, including the armhole curve and sleeve cap.
11. Make any necessary adjustments to the pattern pieces, such as smoothing curves or correcting any discrepancies.

By following these steps, I can create a custom pattern based on an existing t-shirt, allowing me to reproduce or modify the design as desired.
