Wow that is gorgeous. Best use of solids I've ever seen.

as for hanging, I used a curtain rod and those clip on rings.

I make a lot of wall hangings. To get it to hang nicely it needs weight. If you have anything heavier that quilting cotton to use as a backing, that's a cheap idea. Batt it as usual. I use cotton canvas as a backing and quilt through the canvas. Then if you like you can cover the canvas with a thin cotton. Hope I haven't made it sound too confusing. The heavier it is the better the sides lay and the corners flat.

I love your top but I most always like a border and then a narrow binding (1/4 inch front and back). No border gives the look of more modern quilts, if that is what you want it will look great either way. Be sure to put a sleeve on the top and the bottom for a lathing strip. That will help your hanging to hang flat and weight it just a little.

Your quilt is fabulous. I think it has a modern feel to it so I would not put a border on but just bind it. I agree with MaryKatherine about weight helping them to hang better. I find poly battings too light for wall hangings unless they are doubled up with something. W&N tends to quilt up pretty stiff if you lay down enough thread on it which is ideal for a wallhanging. That would be my choice but only if I was going to quilt this pretty heavily. If you wash in cold water and dry flat you shouldn't get any crinkling.

As far as quilting I would go with a very light weight thread, like invisifil or silk. This way the thread won't interfere with your gorgeous hand dyes. I would go with a light gray, mossy gray/green or nude color. Both silk and invisifil tend to sink in and reflect whatever color they are laying on so it shouldn't take away from your striking graphic design in the piecing.

If I had a chance to sink my teeth into this I would quilt graphic straight line accents like ghost quilting of the squares on point in the colored areas. I would do heavy background fill to get those ghost squares to pop up, ala Green Fairy style of quilting. I would leave the QST in gray and white unquilted but SID around them and maybe even in the triangle units that form the squares.

The top is gorgeous. Amazing what precise, careful piecing and beautiful fabric will do for a relatively simple pattern. Very well done.

I like to put a hanging sleeve on the bottom also. Then put a small rod in it for weight to be sure the hanging stays straight

I wouldn't use polyester because that can make a quilt wonky. Just don't over quilt the top. Keep it simple and just stitch in the ditch. I use Hobbs 80/20 for wall quilts as well as bed quilts and table runners. I would do just a normal 2.25" binding, not wider. Since you used more green in the quilt, I would use the dark green for binding. But it never hurts to try different colors in the quilt for binding and take a photo, then you can compare which you think looks best. I usually used a standard small curtain rod to hang my quilts but you can keep it simple and use push pins. There are a number of products to buy to hang a quilt as there are colors in fabric. Pick what will work best for you.

Warm and natural batting is ok to use in wall hanging. To avoid the wrinkly look, I do not wash my wallhanging, but have them dry cleaned. Also I use a 2.5 inch binding, sewing in the hanging sleeve while attaching the binding. To hang the wallhanging, you can use a wooden dowel or a decorative curtain rod. I prefer the curtain rod. I also prefer to have them quilted by a LA,(depends on your budget). Attach your label before having it quilted. Its very lovely. Stunning second design!

Absolutely stunning quilt - love the colors. You did a fantastic job!

First let me say that I love your quilt and I think a grey binding would be perfect, or even a 2" border in grey with the same grey binding. I have made a lot of wall hangings since I began quilting and personally I like using Warm & Natural cotton batting, so that the wall hanging hangs better and straighter. The quilts I've made with polyester batting doesn't appear to have the same stability and tends to ripple. That's just my personal experience.

What a striking quilt!! Very impressive!
