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....
