Plain Grade Wood Stock
This is the lowest quality of wood stock you can get. It is cheaper than all others and may be made of lighter weight wood. Blemishes in the wood grain have been repaired so that they are not visible after finishing.
Fancy
There may be several different grades within the fancy category. Moderately fancy is better than the Plain quality, but AAA is the most beautiful. The levels may be numbered as #4, #3, #2, AA, and AAA. It may also be listed as 5-1 as well as an exhibition.
In either case, the lower the number, the higher the quality.
