Depending on the orientation, the finished look will change.
To determine orientation, grind the block ( or at least an inch of one end) in a more of less round shape. This will let you see the best orientation. I usually set the eyes on the sides. After the curves are added to the handle, this makes a really nice display. Occasionally, when there are few or very small eyes, or when there is curl, I place the quilt/curl pattern on the sides. This will allow the most chatoyancy to show up most boldly.
