Light-, dark-grey and white yarn - 100% Collie underfur, rubbered into two threads. The underfur is spinned with sewing reinforced thread and rubbered into 2 threads.
The work doesn't have any signs of dog wool smell, as it has two stages of washing: firstly the yarn itself is washed, then the finished work goes washing. I don't use cutted wool, only underfur.
