Rauma Finull PT2 (formerly Finullgarn) is 2-ply knitting yarn of 100% pure new wool, very suitable for Fair Isle knitting, but also for other knitting and weaving and felting. Rauma Finull is 100% Norwegian wool and is one of the most environmentally friendly textile fibers in the world! 

This is what used to be referred to as a shetland weight yarn (it can be knit at a slightly looser gauge because it blooms after washing). It has a crisp hand and works well for stranded color designs. The yarn also softens up with washing.

Recommended knitting needles 2.5-3.5 mm
