In fact, canvas and spun silk are made of similar materials, and canvas is thick striped, while spun silk is fine and delicate. Neither of them will be preserved for a long time, because the essence of texture is cloth, so it will obviously fade when exposed to the sun for a long time. Personally, I think it's better to make crystal or Ramina paintings, which look high-grade and can be preserved for a long time, so I know that I am a post-production professional studio.
