Hold the thread with your left hand, lock the edge and start knitting.

Compare the length of the knitting lock needle on the hairpin, and continue to knit the width after it is suitable for the hairpin size.

Weave the lace after it is wide (based on the short needle at the bottom, set up a 3-needle lock needle).

Stick the cloth on the hairpin and the "crochet hairpin" is finished.

Knitting, the process of knitting yarns of various raw materials and varieties through knitting needles and then connecting them into knitted fabrics through series of sleeves. Knitted fabric has soft texture, good wrinkle resistance and air permeability, high extensibility and elasticity, and is comfortable to wear. Knitted products can be used not only for clothing and decoration, but also for industry and agriculture, medical care and national defense.

Knitting is divided into hand knitting and machine knitting. Handmade knitting needles have a long history, exquisite skills and flexible patterns, which have been widely spread and developed among the people.

According to different technological characteristics, knitting production can be divided into weft knitting and warp knitting. In weft knitting production, raw materials can be produced directly on the machine after winding. Each yarn is padded on each needle of the weft knitting machine in turn along the weft direction to form a weft knitted fabric. In warp knitting production, raw materials are wound and warping, yarns are arranged in parallel and wound into warp beams, and then they are produced on the machine.

The yarns are unwound from the warp beam, and each yarn is placed on one or at most two needles of the warp knitting machine in the longitudinal direction to form a warp knitted fabric. On some knitting machines, there are also methods of combining weft knitting with warp knitting.

At this time, two groups of yarns are arranged on the knitting machine, one group is padded according to the warp knitting method, the other group is padded according to the weft knitting method, and the needles make the two groups of yarns form loops together to form a knitted fabric. The loops formed by the same yarn are arranged in the weft direction in the weft knitted fabric and in the warp knitted fabric.
