1 First, before making, measure the size of the human body, the length is from the cervical vertebra to the wrist, and the bust is 3~4 cm. This vest is tight, and the fabric used is elastic knitted fabric. Draw two lines perpendicular to a horizontal line on the paper to determine the length of the clothes. The width of the clothes is 65438+ 0/4 of the bust, and the bust is clear.

2. Make sure that the width of the horizontal collar is 10 cm and the width of the vertical collar is 22 cm. Connect the diagonal to divide the diagonal into three equal parts, and draw a fillet arc through 1/3. If you have no experience, you can use a curvature ruler as an aid.

3. The width of clothes is 25 cm, the width of shoulder strap of hurdle vest is 4 cm, and the shoulder drop is 1 cm.

4. The width of the armhole is equivalent to the bust of 25 cm, and the shoulder point connects the elbow vertex of the armhole with the shoulder point to draw an arc, which can be assisted by a curvature ruler. This completes the previous film.

5. Extend the lower and upper horizontal lines of clothes. The length of the back piece is the same as that of the front piece, and the width of the armhole is the same, so we also extend the armhole line upward.

6. The horizontal collar width of the back piece is 10 cm, and the vertical collar width of the back piece is 2 cm.

7. The back shoulder is 4 cm, and the shoulder strap is the same as the front one, with a width of 4 cm.

8. The width in the middle of the backboard is 5cm. Draw a big arc through the armhole angle to connect the shoulder point with the armhole angle. In this way, the back is finished, and all sides should be threaded.

Precautions for cutting:

1, the cutting edge should be sharp, otherwise it will easily cause the fabric to slip or fluff at the cutting edge, which will increase the cutting difficulty and affect the cutting speed and accuracy. Note: The scissors for cloth cutting and paper cutting should be cleaned separately.

2. The cutting table should be kept level. It is best to spread a cotton blanket or thick cloth on the desktop to increase the friction between the fabric and the desktop, increase the stability of the fabric and facilitate the operation.

3, cutting operation, the left and right hands to hold each other. When entering the knife, the left hand presses the cloth surface and the right hand holds the knife forward. The left hand gesture should follow the progress of the right hand to avoid the sliding of the upper and lower fabrics, which will cause the displacement of the upper and lower layers of symmetrical plates and cause large errors.

For beginners, when cutting smooth fabrics, especially light chemical fiber fabrics in summer, you can first spread a thick blanket on the table and then fold it in half with a pin. The fabric of continuous straight yarn is fixed with table cotton before I cut it with low powder accuracy.

4. Cutting should be carried out in strict accordance with ink lines, and the cutting path should be straight. When cutting a straight line, the scissors mouth should be wide, with the center of the blade and more feeds. When cutting sewing thread with large curvature, such as the front and rear bends of trousers and the front and rear handrails of clothing pieces, the opening of scissors should be small, and the front end of the blade should be used as fast as possible to cut it, while ensuring the roundness of the blade.
