Woven back bench

I started building a different bench, but I decided halfway through that I didn't like my design. I found this, and loved it, so I modified my partially built bench to incorporate the woven back design. I substituted in a few mortise and tenon joints for strength, and used either kreg or waterproof glue for the non-structural joints. The seat bottom is made from 2x4's I resawed in half. I also rounded over the edges of the 'Y' pieces, which I think makes it look a bit more like they're woven together. Thanks for the plans, this is a great addition to my front porch!
