I absolutely love this plan! We're going to build this sectional with 3 corner pieces and 5 seats (and we're using 2 x 4's instead of 1 x 4's). I'm trying to estimate costs and want to know how much varnish would be needed for this project. Anyone have any idea how many gallons?

It will depend somewhat one what varnish you're choosing to use (varnish is a generic term that covers a host of sins). Some are thicker than others, with differences in coverage. But assuming that this will be used outdoors, you'll need to stick to one of the outdoor finishes like a desk stain. A lot of finishes like polyurethane degrade very quickly when left outdoors.

My initial guess would be that one gallon would probably cover you, but if you're going to have a custom color mixed, get two gallons. That's assuming one of the acrylic based deck stains and my own coverage experience.

The penetrating oil stains probably apply at a different rate, but I can't tell you what it is. One of the nice features on modern finishes is that they tend to give you a coverage estimate on the can, in square feet. Square footage calculations for furniture can be a bit tedious, but you can make a good first-guess and work from there.

I would like to make this sectional this year. Would you suggest using pressure treated? I was thinking of something like cedar that I think is naturally moisture resistant (?) but I want to keep the costs down as I know the cushions alone will be expensive. Any suggestions would be appreciated.

Cedar would probably be a nice choice. Nearly anything will work if you put a proper outdoor finish on it and keep that finish maintained. I'm not a big fan of using pressure treated wood unless I'm forced to, because the natural tendency of pressure treated wood is to warp wildly unless it's carefully held down.

If you were to put an outdoor finish on southern yellow pine every couple of years, it would hold up very well. Both my dad and I have several pieces made from SYP and it's working quite well.

Appreciate the feedback. With all of us asking your advice, you are going to need your own blog soon! :)

A mum's day present this year, with our four (almost five) year old helping out with measuring, cutting, drilling, and screwing. Took a bit longer, but he had a great time doing it, and mum really appreciated it. This is the second part of the set, and we made three corners and two armless sectionals.

Still need to stain or paint it, but otherwise great!

Again, thanks for great, easy to follow plans!

**Step four should read "The top on the right sits flush with the legs, the top on the left overhangs the back leg by 2 3/4″ as shown above." NOT 3 1/2". **

Are the materials listed to build only one sèat of the sectional?
