The interchangeable range is highly extensive and exceptionally versatility. Many combinations can be created using the interchangeable products. The range is unique in that it offers both circular and straight needle options which completely revolutionises the knitting experience.

To use Interchangeable Circular Knitting Needles, HiyaHiya tips and cables are combined to make needles which are suitable to several types of work. These are divided into three size groups, miniature (sock), small and large. The miniature and small cables have small, light screw connections whilst the large cables feature chunkier screw connections.
