Most picnic table plans stop at six feet because that's what two leg sets can carry. This one goes the full eight — seats ten, swallows a family reunion — and the design's answer to the extra span is the third A-frame leg set in the middle. Without it, 2x6s over eight feet bow under a potluck; with it, the table is rated for the cousin who sits ON the table. Don't delete the middle legs to save a couple of boards.
The cut list has a gift in it: all nine 2x6 top and seat boards are used at full 8-foot stock length, uncut. That's why an 8-foot table is barely more work than a 6-footer — the only cutting is the leg sets, and those are the same 22-1/2° A-frame geometry repeated three times (legs parallel-cut, supports trapezoid-cut, plus two 15° cross braces).
The assembly tip in step 1 is small and excellent: while screwing a leg set together flat, slip 2x4 scraps under the legs to hold them level with the supports. A-frame parts don't lie flat on their own, and chasing them across the garage floor mid-screw is how joints end up misaligned.
Best finishing advice in the whole source: stain the boards BEFORE cutting and assembly, then touch up tops and cut ends after. Nine 8-foot boards on sawhorses take a fraction of the time that a fully-assembled table with sixty inside corners does — and the pre-finish gets stain into the joint faces where water will someday try to live.

Overall cost: $$$. Lumber prices vary by region, species, and season, so we give a band rather than a figure we would only be pretending to know.

Some parts are longer than a 8 ft board, so there is no honest board count to show here. Open the board plan to pick a longer stock length — it names every part that does not fit.

Stain every board on sawhorses and let it dry before you cut a thing. Fifteen boards flat in the driveway beats one assembled table with sixty inside corners — and stain reaching the future joint faces is real rot protection, not just convenience. Cut ends and tops get a touch-up coat at the end.
Lay two legs and one table support flat, top edges flush, leg feet at the correct spread, and screw with three screws and glue per joint. Slip 2x4 scraps under the legs so everything lies level while you drive — A-frame parts don't sit flat unaided, and this cheap trick is the difference between joints that align and joints that argue.
Flip, position the seat support, screw with three per joint. Build all three sets as clones.
Mark the centers of the seat and table supports. Run one 15° cross brace from an end leg set to the middle set, centered, top edges flush; repeat from the other end to the middle. The braces triangulate the whole undercarriage — the reason this table won't rack when ten people sit down at once.
Set the first two 2x6s on the table supports — side edges flush with the support ends, overhanging each end of the table by 1-1/2" (a 2x4 scrap held vertical is exactly the right gauge). Two screws per board per support.
Then fill in the remaining top boards with even gaps. Uncut 8-foot boards mean the ends are factory-straight — enjoy the one part of the build with no sawdust.
Screw the seat boards to the seat supports the same way — two per joint, even gaps. Sand any raw spots, then run the touch-up coat over tops, seats, and every cut end.
Then invite too many people over on purpose. The middle legs have you covered.
