Hi Sketch,
Beautiful work on that bear. With your burning may I suggest that you burn in the fur lines rather than using a stipplng effect? This will help you create the actual texture of fur so that when you go to paint or stain it will look more natural. If you use a skew tip, depending on what burning system you're using, it will actually cut through the wood in very fine lines to create the texture I'm talking about and then you want to make sure that you're doing your lines in a slight "S" type of curve. If you work from the back forward you will get a nice overlay of the fur actually laying on top of itself.
I hope this helps and I really do love that carving! keep up the wonderful work.
Linda
