We have several woods that we use the majority of the time because they look great and are readily available. Honey Locust is yellow in colour with red heartwood and we have a very abundant source of it. Russian Olive has a white sap wood (outside) and dark to black heartwood (inside) and it's pretty easy to find. Northern Treasure ash has distinctive rings that are slightly different colours and a very soft pith (inner core of the wood), which must be drilled or picked out. At the moment we have a a decent stash of this, but when it's gone, we might not be able to find much. There are several varieties of apple trees that we use; Carrol, Thunderchild, Radiant, and some others if we come across them. It's harder to find these woods, especially in larger sizes, but they are often very unique looking with browns and reds Amur Cherry is quite soft and sometimes too soft to use, but it's red colour with black and brown streaks is beautiful. Walnut and Butternut are similar, but Butternut is a little darker. Both have a pith that will start to fall out on its own once it has dried for a while. Sweetheart Mayday has a neat purple haze surrounding its white pith. Sizes under 1/2" are fairly easy to find, but larger than that is rare.
