Scrounging about the house and yard, I have located sufficient wood for three gobans:
One in 3/4" furniture-grade pine with nice grain and figurings. (I can possibly double it to 1.5", depending on knot holes.)
One in 3/4" high-grade cherry.
One in 2" high-grade cherry! (If I sacrifice some turning stock, which I'm loathe to do.) If I decide to use this, there will also be enough left over to make legs for it as a thin floor board.
I think the cherry boards, though darker than traditional boards, would look awesome with Yunzi jade-luster stones.
So I will start with the pine and work my way up, teaching myself the process as I go.
Pictures to follow, I hope.
