Secret seam on the sewing machine
This seam is in the instructions for sewing machines. But maybe someone has not yet felt his charms.
Usually apply it when the niza is bent, but sometimes in other cases.
The seams are indispensable in the knitted bending - when tensioning does not burst, dots are obtained on the front side, which I like more than the decaying seam (it immediately gives the product a sports or linen look - my perception).
It is also good in the bending of thick fabrics, but it is better not to use it in the products from "dry" tissues, in any case, it does not work beautifully.
Well (but not necessarily) if there is such a foot - then you can scribble "with closed eyes"
Install a zigzag for 2-3 mm, for. Stitch by 4-6 mm.
Loosen the tension of the upper thread to 4.5 ... you need to try on a piece.
If the capture of a zigzag is more, then on the front side it will turn out not the point, but parallel pans-sticks
After the bending is noticed, put it under the paw in such a way as in the photo.
