Incidentally, allow me to share my (immensely unpopular) view regarding what woodcarving consists of. Picture a pie chart, roughly divided into three equal wedges. A fourth, very thin wedge, is also there, but barely perceptable.
Wedge 1- Drawing.
I believe this is the very most important skill for woodcarving. I think this might even be a 50% wedge or more. The need for this skill eclipses all others. If you are to carve, you MUST be skilled at drawing. You can learn. If you are serious about carving, you absolutely must be skilled at drawing.
Wedge 2- Sharpening.
You need to know how to sharpen.
Wedge 3- Actually carving.
That's what you're going to do, isn't it? You need to carve to get used to it. This is LESS important than drawing.
The fourth (tiny) wedge is everything else. This includes, but is not limited to, knowledge of wood characteristics, knowledge of historical styles, knowledge of glue, etc., etc.
Understand: Drawing is producing a two dimensional something or other on a piece of paper with an instrument called a pencil.
Carving is producing a three dimensional something or other on a piece of wood with an instrument called a chisel.
They are the same thing.
I've used a baseball analogy before, so I'll use one more...
Player: I'm a baseball player, and I'm going to be in the World Series.
Fan: Will you play catch with me?
Player: I can't play catch. I am not good at it, I don't know how.
How I learned to carve when I was seventeen:
