NOTE

SEWING PROCESS-SEAM, STITCH

A seam is the line where two pieces of fabric are joined together by sewing. Seams are created by stitching, and they can vary in type and complexity, such as straight seams, French seams, and flat-felled seams. The choice of seam type depends on the desired strength, appearance, and purpose of the final product.

Points to Consider When Choosing a Seam

When choosing a seam for your sewing project, consider the following points:

1. Fabric Type: Different fabrics require different seams. Lightweight fabrics need delicate seams, while heavy fabrics need stronger ones.
2. Seam Strength: Choose a seam that will hold up under the stress and wear of the finished item. Strong seams are essential for areas under tension, like the crotch of pants.
3. Seam Finish: Decide how you want the seam to look on the inside. Some seams leave raw edges that can fray, while others encase the edges neatly.
4. Stretchability: If you're sewing stretchy fabric, choose a seam that can stretch with the fabric, like a zigzag stitch or a serged seam.
5. Visibility: Consider if the seam will be visible on the finished item. Decorative seams can enhance the look, while hidden seams are better for a clean finish.
6. Ease of Sewing: Some seams are more complex and require more skill and time. Choose a seam that matches your sewing ability and the time you have.
7. Purpose of the Item: Think about how the item will be used. For instance, seams on activewear need to be strong and flexible, while seams on home decor items might focus more on appearance.

Types of Seams

The following are the most important types of seams used in sewing:

1. Plain Seam: The most basic and commonly used seam where two pieces of fabric are placed right sides together and stitched along the edge. It is suitable for most garments and general sewing projects.
2. French Seam: A seam that encloses the raw edges, giving a neat finish. It involves sewing the fabric wrong sides together first, trimming, and then sewing right sides together. It is ideal for lightweight or sheer fabrics and for creating a clean, professional finish.
3. Flat-Felled Seam: A strong seam with no raw edges visible. It involves sewing the seam, trimming one edge, folding the other edge over it, and then sewing it down.

It is commonly used in jeans, workwear, and sportswear for strength and durability.

4. Serged (Overlocked) Seam: A seam finished with an overlock stitch using a serger (overlock machine), which trims and encases the raw edges in one step.

It is great for knits and stretchy fabrics, preventing fraying and providing flexibility.

5. Bound Seam: A seam where the raw edges are enclosed with bias tape or binding.

It is used for finishing seams in unlined garments and for decorative purposes, providing a neat and durable edge.
