This is a great experience to try out my very first pyrography in life. It is also called a wood-burning art whereby a heat pen with different pattern of tip is used to create burnt mark on a wood material in order to generate a drawing or any kind of decorative pattern you like.
It is very fun and easy to get into, except lingering of the scorching burning smell result in burning on the surface of the wood.
In my very first self-learning lesson of this subject, I managed to produce two pieces of artworks with the tools. One of them is on a kinda soft single layer wood plate bought from Daiso and it was very easy to burn on the surface without demanding too much of effort. Another one is on a 4-layer plywood bought from a hardware shop which taking me some effort to make it (my fingers were getting really tired after the work).
