I'm always browsing through wood mags at the home center and even subcribe to one. Got one the other day and noticed some jigs they used. Looking at the ply, it looks so much better than what I get. What kind is it and where can I get some? Most of the plys I've used or seen (even at the lumberyard) are I think 6 or 7 ply. Those looked like 10 or 12.
