This is more of a comment than a question but I invite others to comment as well. In my ongoing "learn-as-I-go" LR building I started doing simple carving over the past couple of years. Starting with simple incise carving and progressing to more complex patterns of relief carving. For the most part I've had very few problems, taking time to draw everything out, think ahead of each cut, keep a sharp edge and so on. The stock I'm working on now is giving me fits!
There are no obvious knots but areas where stems grew out of the piece of maple I used and I cannot carve without the wood pulling away. In places it does not matter which direction I try to carve I get the same result, little chips and unevenness. I will end up spending hours cleaning up the carved areas.
I will examine closely and be particular about any stock before I consider decorative carving.
