Alright - time for some pics! We spent a couple weekends on this. We used cedar for the wood and kreg jig for all joints. I only messed up the back rails a little bit by trying to get a cut to fit against the forward-facing edge of the back support instead of anchoring underneath. The cushions came from Lowes (Allen & Roth, $50 for bottom/back after a coupon). After building the sofa, which is HUGE (75" interior width, cushions are 25" ea) my wife asked that I size down the loveseat for her petite frame. I shortened the reclined portion of the seat by 5 or 6" and dropped the height of the arms so that it fit her. I built the single chair to the same specs as the sofa. We primed with SWilliams wood primer (horrible and slow to work with but will pay off) and painted with a green from Lowes since SW wouldn't make the color we wanted in an outdoor finish.
Thanks again for the great plans and guidance along the way. This is my first DIY woodworking project that isn't something to ride bikes on - those are much more forgiving given that they don't need to be aesthetically pleasing and the edges aren't as clean.
Sofa: 10hrs - setup, learn the ins/outs of the miter saw and kreg jig which I've never used either of before. This also included time to re-proportion the plans for the cushions as well as a trip to lowes. Loveseat: 6 hrs - trip to lowes, reconfigure plans, build Chair: 4 hrs - I could do the sofa this fast now.
