I seem to be having difficulties in actually sitting and posting. LOL.
I guess you could probably tell by my several years off?
Anyhow.
I thought I would show how I have been making my binding.
Step 1 - I measure the quilt to see how much I need and then I cut strips the width of the fabric, at 2 1/2" wide. I trim off the selvages and then seam them together into 1 long piece. Then I go to the ironing board and press the seams open and then press the long strip in half. It is now ready to put on the quilt. (This is the method I use for most of my quilts - especially if I give them away to kids)
Step 2 - I sew it to the edge of the top side of the quilted quilt using my walking foot. I use a 1/4" seam allowance. Leave a piece at the beginning about 6" in length. I don't measure it.
Step 3 - coming into the corner, I stop 1/4" from the edge of the quilt. You an mark it with a pin, or just eyeball it. I have occasionally over run the 1/4", and then I have to remove a stitch or two to make it work right. YIKES. But it works.
step 4 - fold the binding back making a triangular looking edge, and then making it even with the edge of the side - fold it down even with the edge of the next side to be sewn. You do this a few times and it gets easier and soon you'll be a pro at it.
step 4 - Now here's your preference. I have heard it both ways. I start at the edge of the new side and sew right on down the new side. Others will tell you to start a 1/4" down. I don't think it matters which method you prefer. They both work. Your corner will be beautiful. Repeat this on all the other corners until you get back to the start of the binding. Stop sewing about 5-6" from where you started.
step 5 - trim off excess binding leaving lent of overlap. I think I have about 4" to 5" extra here. It doesn't have to be measured. Just be sure there's plenty for seaming this.
step 6 - here I fold the binding back on itself and finger press. I don't overlap, and I don't try to make it match perfectly. I prefer a tiny bit of background showing. I think this is about a 1/16". It's very small. Pin it and stitch it on the machine. You can open the fabric and stitch it and press it and fold it back if you want, but you'll probably need to leave more room between the start and stop. I just stitch it while it's folded. This is a very quick method here.
step 7 - this is something I do, I press the seam open and stitch it down along the opening, so the binding is now fully attached. Then I fold the corners down and tack it together. This will keep the corners down and enclosed in the binding and not let them poke out accidentally. Then you can fold the binding around to the back and stitch it down. I forgot to take a photo of this. WHOOPS! The binding is big enough that you can use the machine to sew in the ditch on the front side and catch the back side of the binding. I do this on most of the kids quilts I do. I will hand sew it down at other times.
