We have pulled all the WYS Undyed Aran yarns into a single listing to give you a fuller shade range. The BFL comes in three colours and the Jacob comes in four colours. The yardage varies, 122m for the Jacob Aran and 166m for the BFL Aran, and unlike the Undyed DK the two breeds work to slightly different tensions, the BFL gives 18 sts per 10cm on 5mm needles whereas the Jacobs gives 16 sts per 10cm on 5mm needles. The BFL is lovely and soft, the Jacob is more coarse and rustic. All bear the British Wool Board logo and are made from British sheep and spun in Yorkshire. All are handwash only and will work for felting. Now added - pure Wensleydale Ecru. This is a lustrous, crisp (but not scratchy) breed, nice sheen but not super soft. It gives the same yardage and tension as the BFL.
