Paletteknife and oil on an x-ray: 43 × 35 cm.. ART: Oil FEATURED in Mozambique and neighbouring Countries 16 Nov. 2011. Painting with a knife is a bit like putting butter or jam on bread and produces quite a different result to a brush. Painting knives are excellent for producing textured, impasto work and sweeping areas of flat color as well as tiny shapes of color. I love my palette knife and the freedom it gives me! This could be on any of South Africa ’s coasts, an imagenary painting. Received the 5C Award Banner 4 June 2012.
