Fold and Conquer
- Take the end of your thread in a loop and use your needle to pull the loop into a tight fold.
- Hold the fold firmly in one hand and place the fold into the eye of the needle.
- When a little of the fold is through the eye, pull it through until the loose end from the loop is entirely clear of the eye.

What is a needle used for?
A sewing needle, used for hand-sewing, is a long slender tool with a pointed tip at one end and a hole (or eye) at the other. The earliest needles were made of bone or wood; modern needles are manufactured from high carbon steel wire and are nickel- or 18K gold-plated for corrosion resistance.
What are the 3 types of syringes?
The most common needle gauges are 26 and 27. This gauge range adapts to all three types of injections–intradermal, intramuscular and subcutaneous.
What is a 10 gauge needle used for?
These are regular-walled medical point needles. They are for intramuscular, subcutaneous, and other injections and are available in a wide range of gauges and lengths. They have an oversized chrome plated luer lock hub.

What is the largest gauge needle?
Needles in common medical use range from 7 gauge (the largest) to 33 (the smallest).
Does a 25 gauge needle hurt?
Also, clinical studies have demonstrated that there is no difference in perceived pain between 30-gauge (small gauge), 27-gauge (medium gauge), and 25–gauge (large gauge) needles.
Is a 25 gauge needle big?
Needle Length
Since these are relatively shallow shots, the needle required is small and short—typically one-half to five-eighths of an inch long with a gauge of 25 to 30. Intramuscular injections go directly into a muscle. 20 or 22 G needles that are an inch or an inch-and-a-half-long are usually best.
Is a 21 or 25 gauge needle bigger?
The needle gauge becomes a consideration when the vein of the patient is narrow, fragile, or superficial. In such cases, a gauge size with a LARGER number (eg, 25 G) may be preferred over a routine needle gauge (eg, 21 G) to minimize damage to the blood vessel, as well as minimize the associated pain with collection.
What is a 25 gauge needle used for?
For example, 25G ½ refers to a 25 gauge, ½ inch-long needle. Longer needles (½ inch or longer) are commonly used for intramuscular injections, while shorter (shorter than ½ inch) needles are more often used for intravenous injections. Different sized needles are used for different purposes.
What is the thinnest needle size?
The smallest, thinnest needle is the nano 4mm, 32 gauge needle, which is about as thin as two strands of hair.
Which needle is smaller 25 or 23?
The higher the gauge, the smaller the diameter. For example, a 30 gauge needle has a narrower lumen than a 25 gauge needle.

What is 23 gauge needle used for?
23 Gauge Needles
23g needles, also known as butterflies, are used when a person’s vein is much narrower than average. It is light blue color coded. Despite the phlebotomist’s efforts to anchor the vein, the patient may be unwell or have minimal sites to choose a vein from, requiring a smaller needle.
What is the end of a needle called?
A needle has three parts, the hub, the shaft, and the bevel. The hub is at one end of the needle and is the part that attaches to the syringe. The shaft is the long slender stem of the needle that is beveled at one end to form a point. The hollow bore of the needle shaft is known as the lumen.
