how long u been burning for?
you either need a better burner or more experience doing em,i used to burn n make clocks,i can get sum pics of my work if needed,you can do em freehand but if you're not that good just get some tracing paper find a pic u like trace it n then trace it on to wood before you burn on it,the burner i use has a dial that you can control how dark the burn is,if you'd like to discuss this more please pm me,
to other people please bear in mind burnings not easy and can take hours to do,it took me 10 hours to do a clock before of a bulldog
I've not done it for a while, and used to do it on bamboo. Never used this wood before, so probably have got the burner too hot. Thanks for the tip, I'll turn it down.
I find that if you can copy a picture, you can burn it, though it does take time and some people cant do it at all. My daughter is very artistic, but cant get on with the burner. You can pick up a decent pyrography machine for about £70 - £100, the cheaper ones arent much good. Not cheap to buy, so best if you can find someone and have a go on theirs first.
