just wondering if anyone has any idea where one might be able to find 1/2'' birich plywood.all i can find at lowes or local builders supply is 1/4'' and 3/4''. i wish i cuold find it in 4x8 sheets localy,as i cant realy buy in bulk,just a sheet now and then.1/4'' is just too thin and 3/4'' will work,but it is heavier .one drawback is that i think 1/2'' is about the same price as 3/4''.but 1/2'' would work better for me.thanks
