Complete Analysis of Basic Acupuncture Techniques

（1） Lock needle (braid needle)
Locking needle is one of the basic needle techniques in crochet, usually symbolized as an ellipse in the diagram, with multiple locking needles combined like a chain. Lock needle, also known as braid needle, is represented by the symbol “ch”. When starting the needle, first place the yarn on the index finger of the left hand, fix the other end of the thread with the thumb, and then place the crochet hook in the middle of the two threads on the index finger. Then, turn the crochet hook counterclockwise along the thread once, and there will be a loop on the crochet hook. Finally, fix the loop with the thumb of the left hand, and hang a loop of thread counterclockwise on the crochet hook. Lock pins are generally used as decorative hooks.
（2） Pull out needle
The pulling needle is usually represented by a solid origin on the weaving diagram and is commonly used to hook or lock the edges. Hook and pull the needle in the last circle to make the edge look more neat and attractive. The hook method for pulling out a needle is to insert the needle at the arrow position, wrap the wire, pull out according to the mark, and insert the second needle at the arrow position. The wire should be slowly pulled out.
（3） Short needle
Short needles can be said to be the most common needlework technique. As long as you learn how to hook short needles, you can try challenging them for anything from hair clip film to seat cushions, blankets, and so on. In the diagram, the symbol for a short needle is usually represented by a “x” or “+”. The hooking method of a short needle is as follows: hook out one locking needle (braid needle), start from the first needle, insert a crochet hook into the middle of the second needle, wrap the thread, and pull out the crochet hook from the two loops in the direction of the arrow. Repeat this process until one short needle ends.
（4） Medium length needle
The length of the medium long needle is slightly shorter than that of the long needle, equivalent to the length of two short needles. Medium length needles are generally represented by “T” and are used for weaving bags or hair clips, with a higher density than long needles. Firstly, hook a braid needle and add 2 braid needles at the end as standing needles. Then, wrap the thread and insert the hook into the loop of the 4th braid needle. Thread the thread in the direction indicated by the arrow, and then pull out the thread in the direction indicated by the arrow. This completes a medium length needle.
（5） Long needle
In English terminology, there is a difference between American and British long needles. In the diagram, the symbols for long needles are also different. The hooking method for long needles is relatively complex. First, wrap the thread on the crochet hook multiple times, and then follow specific steps to crochet. For details, please refer to relevant tutorials and diagrams.
In short, mastering these basic needlework techniques is the key to crochet. Through continuous practice and practice, one can proficiently apply these needlework techniques and create more exquisite crochet works.
