FOUR THREAD OVEREDGING STITCH USING 2 NEEDLES

4. FOUR THREAD OVEREDGING STITCH USING 2 NEEDLES

1. Before Sewing

2. Presser Foot Lever

3. Beginning and Ending of Sewing

„

Beginning to sew

After threading is completed, and when the 
threads are not wound around the stitch finger, 
gently draw out the four threads under and 
behind the presser foot, and turn the hand wheel 
towards you by hand two or three times to make 
the thread wind on to the needle plate.

For setting average material, there is no need to 
lower the presser foot lever.
When beginning to sew, push the material just in 
front of the presser foot and it will be fed through. 
For the thick material, lower the presser foot lever, 
place the material under the presser foot, then 
raise the presser foot lever.

Just put your left hand on the material to push 
it slightly until the tip of the fabric comes exactly 
behind the presser foot.
