Ann, You cut off the excess and bind the bottom after you sew it in? Where do you set the top of the zipper in relation to the seam. ie, waist seam line for a facing.
Nancy, thank you for your kind comments.
Yes, I cut off the lower end of the zip after
I've stitched it in. I usually leave a bit less than an inch. I machine one side of the binding in place before trimming the zip, and then fold the binding to cover the cut end and stitch again. Neat enough is OK, no one's going to see it!
There are two options for the top of the zip.
Either - the top can be just a fraction below the top edge so that when fastened the zip pull is right at the edge. I would usually do this at the neckline and sometimes at the waistline.
Or - the top can be about 1/4" below the edge so that a hook and eye can be sewn on for added strength. This isn't quite so invisible but it means that the hook can be fastened before closing the zip; putting less strain on the zip, and making getting dressed a bit easier!
