Hi John, A well-made Baltic Birch plywood is an excellent material, and a pleasure to work with. I just wanted to throw out a caution that you should get BB from a reputable dealer, because there is unfortunately some truly horrible quality "baltic" birch plywood from China (I'm not knocking chinese products in general, just this one) on the market that is prone to warping, and even more unsettling, to delaminating severely. This cheap BB has shown up occasionally at some Home Depot stores, among other places (although some HD stores have apparently carried high quality stuff at some times/locations). If you don't already have a trusted supplier in mind, I would ask a local cabinetmaker for a dealer recommendation (or even for some scraps!). If that is not feasible, I've had good success with the BB carried by Rockler and Woodcraft, though both are fairly expensive, and I only use them when I'm out of stock on a weekend and am willing to pay a premium price for the convenience....
