These are some snack/painting tables that I built for my son Luke's school. The top is plywood with birch veneer with solid birch around the edges, everything else is solid birch. They are oiled and coated with polyurathane. I lucked out on the tops- there is some really interesting grain. Luke was really disappointed that I didn't paint these bright colors, like the old tables that they replaced (as a side note, I'm pretty sure that the old tables were there when I went to this preschool). His teacher was thrilled though, and she bought clear table cloths so that the grain could be seen while the kids eat their snacks.
