How many sheets in a ply

[qquake2k]

Not too many specialty wood outlets in this part of the world (which is the height of irony), so I get my plywood from here and from occasional pilgrimmages to a Michael's. Michael's is good for 1/64" and 1/32" plywood. For some odd reason they don't carry 1/16" plywood, so their next size up is 1/8" which is not quite as high grade at the two smaller sizes. So for sizes other than the two smallest sizes, I get my plywood from National Balsa.

I have also purchased plywood from BMS: http://www.balsamachining.com/

I've gotten some really nice 1/8" and 1/4" birch plywood from my Michael's.
