Yep, Vaughn had it right although in his area, what is the difference between summer or winter??
The way I understand it, the bark is tighter to the wood in the winter due to the sap being down out of the tree. In the summer the sap is between the bark and the wood.
Another little, quick, easy project are snowmen and mushrooms. Especially turned green and bark left on the edge, they twist and move as they dry and get a very natural look to them.
God and family, the rest is icing on the cake.
I'm so far behind, I think I'm in first place.
