The inner corner of a hexagon binding is pretty straightforward, if awkward.
1. Set your machine’s needle to the down position.
2. Lay the binding on, and sew to the corner.
3. Raise presser foot, and turn binding to stay along the edge.
4. Lower presser foot, and continue.
I saw once on Cluck Cluck Sew that she zig zags her edges before binding. I don’t always do that, but I think it’s a great idea and makes for really nice bindings.
When you get to the other side, it is also a simple matter of folding it down and sewing it down, shmooshing as necessary. Shmooshing is a technical term for stitch hacks. It means putting something where you want, even if it resists.
