I haven't played with knives for years. The only classroom experience with them was more than thirty-five years ago in an adult ed oil class. I remember loving the resulting textures and effects, even though I wasn't sure if I were doing it "right." I am still not sure if I am doing it right, but I have been fooling around, and, again/still I am intrigued by the texture. Here are two quick practice attempts. I like them well enough, but I still have a lot to learn, but isn't that always the case?
