This was our second project from Ana's site. There were some bumps in the road (oh, the perils of getting warped 2 by 8 boards to line up perfectly side by side with the Kreg jig). All in all, this table isn't perfect, but it is ours and we love it.
The size of the table in the plans is quite perfect, I'd say. It is long, but fairly narrow. We can sit across from each other as a family of four and still feel cozy, but the table will seat ten if need be.
It is also very, very sturdy....which as a mother to two young boys I appreciate.
This was a 10-20 hour project for us, but we had two children under the age of 5 "helping" and are new to building furniture. I'm certain someone else could build the entire table in an afternoon.
