It's always good to try something new....may I offer some advise? Try using close grained timbers like sycamore, maple or beech. The open, coarse grain of ash makes pyrography much more difficult than it might otherwise be. You'll notice that the line defining the right hand edge of the flower stem has been coerced into following the softer, summer wood in the grain, then skipping across a band of harder, winter wood, before settling back into an adjacent band of summer wood. This effect is greatly reduced if you choose a finer-grained timber.
