If you need plywood in any possible size, shape, color, grain, treatment, etc. your best bet is Anderson Plywood in Culver City. As a bonus, it's conveniently located near Johnnie's Pastrami and Tito's Tacos. Plywood is the greatest wood of all, isn't it? I personally enjoy buying special plywood pieces just to look at in my apartment, and I'm thinking of panelling my Trans Am completely in various plywood grains and stains. I'll let you all know how that goes as soon as it's done.
