This was my first ever DIY project and I have to say I even impressed myself!
I modified the plans slightly as I wanted a longer version of this table. Despite lengthening the table, I found a way to use less wood. Instead of the 5 - 2x6 studs suggested, I bought 3 - 2x6x10s. To accomodate the longer tabletop, I needed to extend the side trim and 1x12, but at 58" top length, these cuts were 47", meaning no extra wood was required (just a little less room for error).
I also used 3/4" cedar strips to mount the 1x12 since I do not have a pocket hole tool (see last photo).
For the finish, I applied Minwax wood conditioner, Dark Walnut for 14 minutes, then Classic Grey on top of the still wet walnut stain for another 10 minutes, followed by two coats of the Fast-Drying Satin Poly.
