Exotic can also be in the eye of the beholder, I've found. A friend told me about a time he was on vacation in the Carribean and watched a worker use a sledge hammer to drive a beam of purpleheart into place. He said it almost made him cry.
In that spirit I would like to tell you about some extremely rare wood that I recently harvested.
That tall spindly thing between the houses is an apple tree. It is shaded from the east by my neighbor's house, from the south by the large pine at the front of the picture, and from the west by large trees on the other side of the yard. As part of our plan to rejuvenate this side of the yard these two trees, along with two more, are coming out. (Before you get too upset about four trees being cut down, you should know that this still leaves eight trees in my front yard alone. If you are still upset, come over and rake leaves this fall.)
There should be enough there for at least eight bowls, although I hear fruit wood is also good for making spokshaves. That rings a bell for some reason...
Whatever I choose to make from this tree, no one else will have wood quite like this, and that's about as exotic as you can get. I have a couple of other 'exotic' woods in my collection already. These pieces are made from a mountain ash that grew in my back yard:
This bowl came from a big leaf maple burl that grew in the back alley two doors down.
