Jimmy @jimmyG, my "GoTo Wood" for now and the foreseeable future is free wood. I have a substantial stockpile that friends have given me, one who downsized and didn't have room for his woodworking shop, one who worked at a cabinet makers shop and gave me a bunch of cutoffs and one who makes furniture out of mesquite and gave me some of his cutoffs. I am now refusing free wood as I don't have room to store any more. It is in all sizes and shapes and I resaw and plane and glue to get panels for scrolling. For varieties, I have mesquite, acacia, red oak, white oak, cherry, walnut, maple, poplar, pecan and probably a few others.
I also have a supply of really small, really exotic cutoffs from a guitar maker friend, but these are all small pieces and hard to use for scrolling. If I ever take up intarsia (on my list of things I would like to do) I will be able to use many of these.
Now if I can just find the time to do scrolling.
