Free! Mini-Episode 59: Grading, Trimming, and Notching, Oh My!
Digest
This podcast episode covers crucial sewing techniques focusing on seam allowance manipulation for improved garment quality. It begins by explaining trimming, grading, and notching seam allowances, emphasizing the purpose and methods for each, including considerations for different fabric types. The discussion includes a debate on personal preferences regarding trimming seam allowances. The episode then delves into grading seam allowances to reduce bulk, particularly in areas with multiple layers, highlighting different grading methods and the importance of sharp scissors. The hosts also discuss when grading might be skipped (e.g., lightweight fabrics). Finally, the podcast explains notching and clipping techniques for creating smooth curves in garments, detailing how to handle concave and convex curves, and offering tips for various fabric weights and seam intersections. Alternative techniques for sharp corners are also presented. The overall message stresses the importance of these techniques for achieving a professional finish, while acknowledging exceptions based on fabric type and garment design.

Q&A
Why do patterns often use a 5/8\" seam allowance when sewists often trim them down?
A wider seam allowance allows for alterations, handling less stable fabrics, and trimming fraying before finishing.
What are the benefits of grading seam allowances?
Grading reduces bulk, creating a smoother, more professional finish, especially in multi-layered areas.
How do I properly notch and clip curved seams?
Clip concave curves and notch convex curves close to the stitching, avoiding cutting the stitches. Adjust technique based on fabric type and weight.
Should I always trim, grade, and notch my seams?
These techniques generally improve the finish but can be omitted for lightweight or delicate fabrics or if extra seam allowance is desired for alterations.

We're bringing this mini-episode out from behind the paywall as a treat for you! It was originally released in September 2024.
This mini-episode is about bread-and-butter sewing techniques that reduce bulk. We review the basics of grading, trimming, and notching, plus some more advanced and unexpected techniques that will give you a great finish. Caroline and Helen learn a lot about each other in this episode…👀 Let us know: do you trim your seams every time, or only when the pattern instructs you to?
