We used the farmhouse table plans from this website, and modified the length and width. The finished length is about 8 1/3' long (100") and 45" wide.
This was our first build and my husband and I learned a lot! We could not find untreated 4x4s ANYWHERE in our area. We searched for days and called probably 10-15 places. We were just going to build with 2x4s, but my husband's work ended up having some pallets that used 4x4s come in with a shipment. They were not in the best shape, but we wanted it to look rustic so we weren't too concerned. Also, our 2x6s were a little warped, so they bow down at the ends. We searched through piles and we didn't really notice until they were on (breadboards). We did buy a Kreg Jig Kit and are so glad we did! We have used it for other projects and can't wait to use it for more. Such a great purchase!
I learned to ALWAYS do a test piece of stain first. This was new to us. We stained it the first time, and then had it spray coated with polyurethane (my stepfather does cabinets). I hated the finish! So I ended up spending an entire day (from 8 in the morning until midnight) stripping the 3 coats of polyurethane and stain. We could not get it all out, but got most of it. We then re-stained it with a lighter color (custom stain left over from our kitchen) and finished it with Minwax Wipe-On Poly. I like the more natural finish much better. If I could talk my husband into it, I would build another one so I could get the stain right.
Overall, I'm pleased with how it came out! The plans were easy to follow, and not hard to modify using a little math.
