Circular needles, fixed or interchangeable, for seamless knitting

Circular needles are a type of knitting needle consisting of two points joined by a flexible cable. They are designed for knitting in the round (seamless) or flat (as if they were straight needles), distributing the weight of the fabric along the cable, which makes them more comfortable to use.

They are especially useful for tubular garments such as hats, collars, jumpers, sleeves or socks, although they are also used for blankets, shawls or large projects. Their use has grown in popularity because they allow advanced techniques such as magic loop or top-down.

The main difference is in the type of connection between the cable and the tips:

• ▷ Fixed circular needles come with the cable already attached and cannot be separated. They are simple, economical and practical for those who always use the same length.
• ▷ Interchangeable circular needles allow you to connect and disconnect cables and tips of different sizes. They are versatile and very useful for knitters who work in different formats.

If you plan to knit regularly, interchangeable needles may be a more cost-effective investment in the medium term.

The choice of cable depends on the type and size of the project. As a guide:

• 👒 40–60 cm: hats, neck warmers, sleeves.
• 👕 80–100 cm: jumpers, bodysuits, adult garments.
• 🧣 120–150 cm: shawls, blankets, magic loop techniques.

It is preferable to use longer cables if you plan to work with techniques that require stitch movement or if you don't mind excess cable.

Yes. Although they are designed for circular knitting, circular needles can also be used for flat knitting, just like straight needles. Simply turn the work over when you reach the end of the row, as you would with traditional needles.

This technique is especially useful when working on large pieces (such as a blanket or jumper) because the weight rests on the cable, preventing strain on the wrists.

Circular needles allow for multiple techniques that are not possible or are uncomfortable with straight needles:

• ▷ Magic loop: for knitting small pieces with long cables.
• ▷ Two at a time: for knitting two sleeves or socks at the same time.
• ▷ Top-down: seamless jumpers from the neck down.
• ▷ Circular yoke: continuous circular yoke.

These techniques optimise time, improve the finish and eliminate seams.

You can find circular needles in different materials:

• ▷ Wood and bamboo: warm to the touch, good grip, ideal for beginners.
• ▷ Metal (aluminium or steel): smooth surface, ideal for fast knitters.
• ▷ Carbon or technical plastics: lightweight, quiet and durable, very ergonomic.

The material affects both the speed and the knitting experience, so choosing the right one can make a big difference.

A good set of interchangeable circular needles should include:

• ▷ Several pairs of tips in different thicknesses.
• ▷ Cables of various lengths.
• ▷ Connectors and safety stoppers.
• ▷ Keys or tools for tightening joints.
• ▷ Organiser case.

It is also important to check that the screw thread is solid and that the cables do not twist easily.

• ✅ Greater ergonomics and comfort when working with heavy pieces.
• ✅ Less strain on wrists and arms.
• ✅ Easier to transport.
• ✅ Allow for seamless circular knitting.
• ✅ Ideal for modern techniques such as top-down or magic loop.

Their versatility makes them a favourite choice for advanced knitters.

Yes, especially wooden or bamboo models, which offer more friction and control over the yarn. In addition, they are very versatile as they allow you to knit both flat and circular.

It is best to start with an 80 cm cable of medium thickness (4–5 mm) and practise first with simple projects such as collars or scarves.

Knitters often rely on specialised brands such as:

• ▷ KnitPro: wide variety of sets, cables and tips.
• ▷ ChiaoGoo: known for the quality of their cables and precision.
• ▷ Tulip, Clover or Prym: highly regarded for their ergonomics.
• ▷ Pony or Opry: affordable and reliable options for all levels.
