This post will be short and sweet, because there's really only one part of this process that might be foreign to you (sorting out the binding at the curved corners).
To prepare the backing, you'll cut your yardage into two 1 1/2 yard pieces. Sew together down the length to make one large panel. Baste, quilt (I did free motion) and trim off the excess batting and backing.
Prepare your bias binding using your preferred method. Personally, I love these instructions from The Dread Pirate Rodgers. Her method looks a little scary at first, but her instructions are amazingly detailed, informative, and there's virtually no fabric waste, which I love.
Start pinning your binding on one of the end rings, making sure to leave a tail. It's best to start at an end because you'll have plenty of room (without any pesky corners) to attach your tail ends once you've worked your way around the quilt top.
Pin until you reach a corner. Now there may be a better way to do this, but this method is what's worked well for me in the past. Make a baby miter, finger press, and pin in place. You don't want to do a full-on miter with all the folding (like you would with a regular square corner) because it gathers up way too much fabric at the corner, and it's nearly impossible to miter the back side.
You may have to work your binding a little bit to get everything in place before you pin.
Once you've finished pinning the entire top and begin sewing your binding down, this is how you'll need to navigate the corner. I made 1/2" binding, so I sewed until I was 1/2" above the corner and pivoted to go down the next curve.
Once you've finished sewing down the top of the binding and start flipping it toward the back, here's how you'll situate the fabric at the corners. At your first corner, go ahead and clip down the binding that's on either side of the corner into it's rightful place, so there's not a bunch of excess fabric floating around. Grab the fabric bunched at the corner...
...and following the natural inclination of the fabric from the miter you made earlier, tuck the right side under the left using your finger until there's no excess and the binding wants to lay flat with no puckering. Once you have the front in place, the binding should naturally fall into place on the back as you fold it over.
If you machine sew the back of your binding (like me), you'll sew down one side and pivot at the corner, just like you did for the top.
And voila! You're finished! I immediately wash and dry my quilts after binding because it crinkles up nicely and hides most of my flaws - there's nothing like a good run through the machine to hide your quilting sins ;)
And here's a crapload of pictures. I document every last inch of my Double Wedding Ring quilts because they're so difficult to make!
