I was afraid my spoon blanks would dry out before I got to them, which is why I was storing them in a plastic bag full of chips from the carving process. Then I was afraid that fungus would get working on the blanks before I got them finished up, so I decided to wrap them in plastic and freeze them. The idea is that if the wood is below freezing temperature, the fungus will at least slow down until I can carve the wood. Those little white packages, lower left in my freezer, are my spoon blanks:
Will this work? I don't know, it's an experiment. I think it probably will. I know that wood can dry out while frozen (water can sublimate). Hopefully, double-wrapping the blanks in plastic will keep enough water in the wood to be easy to carve, while being frozen will slow the fungus down enough so I won't be working spalted wood (unless I want to, of course).
I'll keep you posted!
