So I just finished building this bench: https://www.ana-white.com/woodworking-projects/fancy-x-farmhouse-bench?page=0
I like the bench everything came together really well and everything seems square. I built the full 8 foot bench and my concern is I have a slight wobble in it from left to right. I'm trying to figure out where to put some diagonal cross-braces and I'm not entirely sure where the best places would be. I'm pretty new to this woodworking thing so if I could get a little advice that be great. Thank you.
