I wanted to know more of this carving/decoration and hence surfing on the internet found that this art is called as “thai carving”. I found some useful sites that help one to learn making vegetable and fruit carvings. I have listed them below. The first one is a list showing links to YouTube videos for beginners to experts. The other sites are also quite useful. Try them and add vegetable carving to your hobby list.
