You can practice your pyrography art on unfinished wood from Amazon.
Just starting out?
Walnut Hollow Vera Tool is the best choice for beginners or anyone looking to make your girlfriend that last minute anniversary plaque that has both your names on it + “4ever”. On top of being incredibly affordable, this is a great learning kit which actually lasts (I still have mine after 2 years), but because it is a solid point tool it has a longer heat-up and cool-down time and also more likely to snag on parts of raised wood (see first paragraph for why that’s no bueno). If that’s not a deal breaker for you then I’d definitely recommend starting with this tool.
