There are two schools of thought on carving pine:

  1. Only carve kiln dried wood, because it is stable and cracking/hardening has been controlled or stopped.
  2. Only carve green wood or pine that is soaking wet (like pulled right out of a bucket of water).

If you are getting pine from the source (the tree), try to use the sap wood (closest to the bark). Soaking will limit the cracks there.

Worth mentioning is that BASSWOOD is often the wood of choice for most carvers not pine.
