[Woodcarver] Bark carving question - fantasy houses

[Victor Hamburger]

I have a question for those who have read "Carving Found wood", or seen the
fantasy houses that Rick Jensen carves in bark.  I have a couple of small pieces
of bark that would fit well with this style of carving.  

My question is, how do you "lay out" the design?  Start by removing the rough
bark only where you know you don't need it, and then carve further back on the
rough bark as you expand the carving? Or do a more complete pattern first, so
you can remove most of the excess rough bark first and then get into the final
shapes and then details? The book doesn't go into a lot of detail on this style
of bark carving and I would be interested in various opinions.  Anyone on the
list taken any classes with Rick on these houses?  

Thanks,	Vic H
