Stay stitching is a crucial step in sewing, especially when working with certain fabric cuts or types. Its primary function is to protect the shape of your fabric pieces before they are sewn together.
According to sewing resources, the exact answer to the question "What is the purpose of stay stitching?" is: to stabilize the pattern piece and keep it from losing its shape due to repeated handling.
Why Stay Stitch?
Handling fabric pieces, particularly those cut on a curve (like necklines or armholes) or on the bias, can easily cause them to stretch and distort. This distortion can lead to garments that don't fit correctly or hang properly.
Here's a breakdown of its importance:
- Prevents Stretching: Delicate or bias-cut edges are prone to stretching when touched, pinned, or moved. Stay stitching creates a line of security near the raw edge, preventing this unwanted give.
- Maintains Shape: By stabilizing the edge, stay stitching ensures that curved pieces retain their intended shape, making assembly easier and more accurate.
- Improves Accuracy: Working with stable edges leads to more precise seams and a better-fitting final garment.
When and Where to Stay Stitch
Ideally, stay stitching should be done right after cutting out your pattern pieces, as the fabric is "at its freshest" before any significant handling occurs. Common areas that require stay stitching include:
- Necklines (especially curved ones)
- Armholes
- Waistline curves
- Shoulder seams (sometimes)
Stay stitching is typically done with a regular straight stitch, often slightly shorter than your normal sewing stitch, and placed just inside the seam line (e.g., 1/8 inch or 3mm away from the raw edge).
Fabric Types
While often associated with woven fabrics, "any fabric, even knits, can benefit from staystitching" to maintain its shape during the sewing process.
In summary, stay stitching is a preventative measure that saves you frustration later by preserving the integrity and shape of your fabric pieces right from the start.
