First, how to make the waist beautiful
Trim the corner seam, and the trimmed seam is 0.3cm away from the corner sharp line. According to the weaving accuracy of the fabric, the loose fabric should not be trimmed too much to prevent the corners from being damaged. Turn it over again and it will be easy and smooth.
Second, how to dig the bag beautifully
Digging bags is also the key and difficult point. How to become beautiful? I won't talk about it here. Everyone in this business knows. How to ensure that corners are everywhere? It says here that there is a rescue production on the digging bag.
First of all, accurately locate on the opposite side of the cut piece (the four corners of the dug bag). After saving, when pressing the fillet, you can use the template of standard width and pocket width to compare the seam, but the experienced lathe union will do it beautifully without the template. They will sew the loin first, and then sew the loin. One more stitch will be sewn at both ends of the upper die (keeping the position corresponding to the sewing points at both ends of the lower die), and the corners of the bag will not be trapezoidal when turned over. Pay attention to two points: it is best to close the bag in the middle of its width. If the bag is too high, it will not look good; if it is too low, it will not look good. The cutting angle must be in place. Don't cut it too much or misplace it. It's best to cut it a little farther from the seam, so that all broken lines are easy to break corners and rough corners. If the cutting is not in place, the corners will not be straight.
Third, how to make beautiful arc parts
In fact, the way to turn the arc is very simple, that is, cut 0.2 along the arc after sewing face to face. 0.3cm small gap, depending on the radian, as shown in the above figure, the bag mouth can be evenly cut 5 knives at the bend, and then turned over and pressed to open the line, which will be smooth and flat without wrinkling.
