I followed Ana's plans http://ana-white.com/2012/06/plans/fancy-x-farmhouse-table Total cost for me was $150 thats lumber,screws and stain. Total time for me was approx 6 hours and it was most time consuming for the legs. I build this in my yard as I don't have a shop. I put my old table saw on a pallet and my chop saw on the table saw. I altered a couple pieces to make the look different and bulkier for me. This is going to make an excellent gift. I just need to put a finish on it and seal it. Oh and I made mine from spruce. *Update* So we finally were able to put a finish on it with a 24 hour window of no rain. We used 2 coats Behr Cedar stain. It is an all in 1 and turned out beautiful.
Not pictured, but I did add a strip of wood under each end to pull the board ends flush with one another. I used 2 1x2's with ends cut at 45 degrees. Length was cut to fit. This isn't something that was in the build plans, but it was very hot out when I was building this and the boards were starting to run up and down if you can see that in the photos.
