I have chosen this image of a tree stump beacuse as as well as texture it also shows line and tone, this made into an art study would be breathtaking as the image has different tones of brown and different layers in the wood.
A rope has tactile texture because you can physically touch the grooves between the twisted strands. Although, a picture of a rope only has visual texture. (unless you are physically holding a print of the picture of rope)
Art in Nature - natural sea coral with beautiful rippling textures; organic inspirations for design I love the layering and texture in these corals- reminds me of mushroom etchings i have already produced.
