The wool for our felt comes from sheep in New Zealand and Australia and is mulesing-free. Mulesing is a controversial process that is unfortunately still practiced in Australia, but only with Merino sheep. The Australian wool from our German felt producer is 100% Merino wool free. This creates a mixture of New Zealand Merino wool and Australian non-Merino wool, which also has an impact on the particularly good and consistent quality of our felt. It is even, stable and pleasant to the touch.
