The better a woollen fabric felts, the more wind resistant it gets. Instead of using chemicals to get a better felt, we found a traditional soap from Hälsinge Såpa.
The soap from Hälsinge Såpa is made from Swedish pine trees. It has the same effect of altering the PH of the water for a better felt, but entirely naturally.
Hälslinge spåa has existed since 1992 and they produce soap in the traditional way with the natural oil from pine trees. No perfume or other ingredients are added.
The soap was sent to Sjuhäradbygdens Färgeri where they used it in the machine for fabric felting.
