[Woodcarver] copyright rules etc.

Dear list members,
I belong to a small carving club in rural North Carolina.We recently 
began talking about selling carvings.
Most of us being new at this, we talked about what you could and could 
not legally sell. Most of us have purchased rough outs with instructions
from time to time. All of us have copied free patterns from the 
internet. All of us have made carvings from patterns and instructions 
found in the carving magazines we purchase.
Morally and probably legally? we need to give credit for rough out 
and/or pattern, but the question which we really have is:
What can a person legally sell in a show or at a craft fair or in an art 
gallery as a conscientious,  wood carver concerned about the  state of 
the art?
                                                                        
            Thank you in advance for your replies, and as I have learned 
, Keep Them Sharp,
                                                                                                                                                                                   
Larry,
