Felting means to get involved with the natural substance wool, you get grounded, patient and even keep your fitness.
Creating felt pictures, or 'painting with wool' is a slow process that requires practice, persistence, and focus. But every time you succeed you are in seventh heaven!
For my felt paintings, I prefer Tiroler Bergschaf and Maori wool, but there are many more options for other felting projects, weaving and spinning - f.i. Jacob, Bluefaced Leicester, Wensleydale, Manx Loaghtan, Falkland, Corriedale, Shetland, Kap-Merino, New Zealand-Merino, Chubut, Drente Heideschaap, and Texel. The different textures are fascinating, and I use each material when it's properties are required.

A felt painting doesn't have to be robust in the first place. Sometimes a motif looks perfect before it is completely fulled. As soon as your work meets your imagination, you can call it finished.
All fibers (ferns, grass, bark, feathers) that may not be suitable for heavily used everyday objects can be used in felt paintings - the options are endless.
