Yep, Clark's is a good place for our purposes, depending on what you're looking fore. They carry okoume, and I'd guess the other plywoods we occasionally use as well, and I'd check them against Houston Hardwoods for price before buying. They also carry clear
cedar in rough cut form up to 6-by, but watch out, it ain't cheap. Very consistent coloration too, take note if you're looking for lotsa contrast. I end up sticking with McCoy's for my cedar. They have the other good stuff like basswood, cypress, etc.
Most importantly, they welcome hand-selecting. Leave neat stacks behind, please.
There was a cedar supplier up in the Conroe or Huntsville area mentioned some time back, and I failed to write it down. Anyone know the name?
