I loved this plan for sturdy, yet economical Adirondack chairs. They were exactly what I needed for one of our Airbnbs. I liked the look of smaller back and seat boards, so I used 1x4s in place of 1x10s. The seat spacing worked out on the seat but on the back I had to rip one of the boards on the back down to 2.5 inches or so for it all to to fit. If I make them again, I’d probably just add a 2 inches or so to the length of the back 2x4s so the back board spacing would work out.
Thanks again, Ana, for proving such great plans for us all.
