A seam is made when two or more layers of fabric are stitched together.
A seam
Three self-neatened seams include the French seam, the flat-felled seam, and the bias-bound seam. A French seam encloses the raw edges within a folded seam, providing a clean finish ideal for lightweight fabrics. The flat-felled seam features one seam allowance folded over the other and stitched down, creating a strong, durable seam commonly used in denim. The bias-bound seam encases the raw edges in bias tape, offering a neat finish while allowing for flexibility in fabric types.
Jeans are constructed with several seaming techniques but the seam you are probably inquiring about is the "flat-fell" seam. Sewmetheway
.... This question is open to interpretation. Knits and spandex sportwear/swimwear is finished on a serger or overlock machine. Two neat stitch lines appear on the 'right' side of the garment. When you reverse the fabric you see that these stitch lines are connected (overlocked). Double stitched may refer to two rows of stitching you typically see on Denim jeans. This is a flat felled seam- no loose ends or seams to overcast to prevent the denim from unravelling. A double stitched seam may be straight stitching on a seam and then stitching another row alongside it.
After the seam is sewn, a seam finish can be applied to the outside edges of the seam allowances to keep them looking neat and prevent fraying. Examples of seam finishes are a zig-zag stitch, using pinking shears for a pinked finish, french seams, flat-felled seams, etc.
To finish a seam by hand effectively, use a slip stitch or whip stitch to secure the raw edges together neatly. Trim any excess fabric and press the seam flat for a professional finish.
A lapped seam is a type of seam where one fabric layer is placed over another and then stitched together. It is commonly used in garments and textiles to create strong, durable, and neat seams, often seen in jeans or workwear.
To finish sewing a seam for a professional and polished look, you can use techniques like backstitching at the beginning and end of the seam, trimming excess fabric, pressing the seam open or to one side, and using a zigzag stitch or serger to prevent fraying.
Cricket balls have an outer cover made of four pieces of leather. In the old days, such coverings had to be stitched in order to keep them from falling apart while in use. The stitched seam continues to be on the cricket ball today because it has become an important aspect of bowling technique.
In sewing, seams are formed by joining the fabric together to create a finished product.
