The temperature control on the woodburner helps a lot for that. It takes a lot of practice though.
I haven't personally tried cherry wood yet. I think that may be too hard. I use basswood (there's other names for it in other countries). I like it because it's soft and smooth and doesn't have a lot of grain in the wood. I sand it before also so I can get the best smoothness I can while burning it.
I finally found the right way to take pictures of my woodburnings also. In the last month or so. Which kind of sucks because when I look at my older woodburnings I see how bad the quality of the photo is... Oh well.
