Thank you very much! It is definitely a fun medium to work with, though not very forgiving
There are tools to start it in every major hobby shop (usually) I would start with one of those, they cost about 30.00usd.
The tool (a pyrography pen) is very similar to a soldering iron just with different tips to use for shading, lines, detail etc....
Depending on the piece, I will either transfer the image onto the wood, or just freehand it
If you have any other questions please let me know! I'd be happy to answer them for you!
