It is used to fasten the raw edges either straight or curved that are to be turned in. It is always worked from the wrong side of the garment with a single strand matching thread. The width of the hems and method of hemming vary as per the texture and type of the garment.
Hemming is of two types
Quick or Blind Hemming: This is the easiest and quickest method of hemming generally used by tailors. The stitches are visible as slanting stitches on the wrong side of the cloth.
Invisible or Slip Hemming: This is neither visible from wrong side nor from the right side. This is often referred to as slipstitch hemming or slip-stitching, and is used for hems, folds and facings where invisibility is more important than durability. Attachment of the lining to the coat fabric, holding two creased edges, finishing of the edges of reversible fabrics etc., are some of the applications of the stitch.
