I’m getting more adventurous with my serger, a Elna Pro 704 Dex. This serger can sew fourteen different stitches*, but I’m having trouble understanding the differences between some of them.
For example, one stitch is called “4 Thread.” Four-thread *what*?–“overcast”? “Overlock”?
But they can’t mean “4-Thread Overcast” because there are already stitches that have “overcast” in their names. Assuming that they mean “4-Thread Overlock”–then how is an overlock stitch different from an overcast? It seems to me that every *overlock* stitch also *overcasts* the fabric edge to prevent raveling.
The black-and-white pictures in the manual don’t help much, so I’m going to sew a sample of each stitch, using different colors for the needles and loopers.
*The fourteen stitches listed in the manual are:
3 Thread wide
Overcast 2 wide
Narrow Hem 3
Rolled Hem 3
Rolled Hem 2
