Slightly modified the farmhouse table plans to build the top out of 6 inch pine shiplap, its thinner than the farmhouse plans (its 3/4inch), but I liked the rough cut on the top surface, and overlapping edges made for a great fit.
I cut the outside edge boards down to 4inch wide, and then mitred the corners to act as a frame for the 6 inch boards. I will build copper corner protectors.
Finish was: pre-conditioner on the wood, 3 coats of minwax weathered oak stain, 3 coats of polyurethane. Sanded the benches between coats, but not the table, as the table has a rough surface.
benches are 2x6 fir boards, cut the long edges off on a table saw to make them join better, as I dont have a jointer. Same finish applied as the table.
Table is 8 feet long, 38 inches wide. seats 10 comfortably.
It was half finished in my garage for several months, in which time I used it as a workbench - so it has plenty of authentic weathering dings and dents.
It was my first project, as I have only recently moved into a house with a garage.
Loved the construction part, hated the finishing steps.
