How to sew an Overlock Blind Hem

The excess fabric is trimmed and the hem is sewn and 
the raw edges are overlocked in one operation.
The overlock blind hem is best suited for sewing knit 
wear. It provides a durable finish that is almost 
invisible.
Use overlock right needle and adjust machine for a 
narrow 3-Thread overlock stitch. (Refer page 45)

 

–

Set the stitch length dial at 4.

 

–

Fold the hem to the wrong side of the fabric, 
then back to the right side with 6 mm (1/4 inch) 
beyond the fold.

 

–

Stitch on the extended hem edge, allowing the 
machine needle to barely catch the edge of the 
fold.

PLEASE NOTE:

For this technique also a 3-thread rolled hm or a 
3-thread narrow seam can be used.

PLEASE NOTE:

An optional blindstitch foot is available (Refer 
page 70).

How to sew Pin Tucks

 

–

Sew decorative pin tucks on the fabric before 
cutting out the garment.

 

–

Use overlock right needle and adjust machine 
for a narrow 3-Thread overlock stitch. (Refer 
page 45)

 

–

Place the movable upper knife in the nonworking 
position. (Refer page 13)

 

–

Mark the fabric with the desired number of pin 
tucks using a water-soluble fabric marker.
