12 Serged seam (Fig 43)
Fig 43

You need a Serger or Overlock machine for this seam. In this seam instead of a plain straight stitch the serger
stitch is used on the seams and the seam allowance is trimmed by the machine.This seam gives stretch and
flexibility to the seam.
This seam can be used under the following conditions
1 If it is not important that seams are kept flat or open.
2 For loose garments
3 On lightweight fabrics
4 When sewing with knits
How to sew a Serged seam
Place right sides of the fabrics together matching the stitching lines.
Keep the fabric under the needle
The serger will automatically trim the seam allowance and enclose the fabric edges in a thread.
A 3 thread serged seam will give stretch to the seam and a 4 thread serged seam will give strength to the seam.
A 3 thread serged seam is usually used for knit fabrics for its stretching property.
13 Slot Seam
This seam which is similar to the lapped seam, is used for its functional as well as decorative properties.
How to sew a slot seam
Keep a 1 1/2″ wide cloth, as long as the seam, under the seams. This is used as a backing piece kept between
the two fabric lapped along the stitching line. (Fig 44 & 45)
