Apologies: The title you see in the video, '2 Curves', should read '3 Curves'. (This is indeed the 3rd video workshop in this project.)
As in the previous video in this project, there are other videos here on Woodcarving Workshop that will pack out the technique I'm showing you. In particular:
Again, it's the curved surface on which you are working that makes this a tricky bit of carving. Trust your eye as much as the drawn line and cut to the edges carefully—sneak up on them.
You get a close up, almost train-of-thought, style of teaching as I carve so apologies for the heavy breathing: I had a cold and was sniffling a bit. But the show must go on!
When you think you've done, again, change the lighting and check the edges.
