1. What are seams?
In sewing, a seam is the join where two or more layers of fabric, leather, or other materials are held together with stitches.
Prior to the invention of the sewing machine, all sewing was done by hand. Seams in modern mass-produced household
textiles, sporting goods, and ready clothing are sewn by computerized machines, while
home shoemaking, dressmaking, quilting, crafts, haute couture and tailoring may use a combination of hand and machine
sewing.[1]
In clothing construction, seams are classified by their type (plain, lapped, abutted, or French seams []
) and position in the
finished garment (center back seam, inseam, side seam). Seams are finished with a variety of techniques to prevent raveling
of raw fabric edges and to neaten the inside of garments.
All basics seams used in clothing construction are variants on four basic types of seams.
 Plain seams
 French seams
 Flat or abutted seams
 Lapped seams
A plain seam is the most common type of machine-sewn seam. It joins two pieces of fabric together face-to-face by
sewing through both pieces, leaving a seam allowance with raw edges inside the work. The seam allowance usually
requires some sort of seam finish to prevent raveling.

2. In a French seam, the raw edges of the fabric are fully enclosed for a neat finish. The seam is first sewn with
wrong sides together, and then the seam allowances are trimmed and pressed. A second seam is sewn with
right sides together, enclosing the raw edges of the original seam.
In a flat or abutted seam, two pieces of fabric are joined edge-to edge with no overlap and sewn with hand
or machine stitching that encloses the raw edges. Antique or old German seam is the 19th century name for
a hand-sewn flat seam that joins two pieces of at their selvages. This type of construction is found in
traditional linen garments such as shirts and chemises, and in hand-made sheets pieced from
narrow loom widths of linen.
In a lapped seam, the two layers overlap with the wrong side of the top layer laid against the right side of the
lower layer. Lapped seams are typically used for bulky materials that do not ravel, such as leather and felt.

3. Finish Seams
Isn’t it always about the details? This thought particularly applies with sewing. Especially in the area of
finishing seams. Finished seams on any project prevents unraveling and makes the inside look much nicer.
Using serge is one of the best ways to get finished seams on a sewing project. What if you don’t own serge?
Well, there are many ways to Finish Seams without Serge.
