I'll keep that in mind. :)
Quartersawn boards are cut radially, from the center of the log to the bark. Flat sawn boards are tangential to the outside of the tree. Rift sawing is somewhere in the middle.
The pattern of sycamore is strongly influenced by the cut. This is because of the striking medullary rays that radiate from the center of the tree to the cambium layer on the outside.
