Felt making is a very ancient craft and dates back to the beginnings of civilisation. Wool fibres are felted using moisture, friction and heat. As the wool shrinks the fibres interlock and mat together.
I have used traditional hand rolling. Hand rolling is very versatile as a wide range of qualities, densities and finished can be obtained. The fibres are layered in an area of chosen size and shape, upon a bamboo mat. The batt is then wetted with soapy water and rolled in the mat. The batt must be carefully turned, rolled and measured regularly.
Slippers shape by hand and leave to dry on special shoe lasts. Soles covered with natural latex (not to slippery. It’s safe to walk).
