Kim asked how do I use part of a zipper to edge my fob shown back on some of my previous my posts........ I found many different ways on the Internet but this is the method I am using, so Kim here are some photos that might explain
First I run a tacking stitch along the fabric close to the zip teeth, this will ease the fabric later making it lie neater on the inside, I cut most of the fabric off, I have seen one example on the internet where they cut right back against the teeth... I think having a small amount of fabric makes it easier to handle.
I have a circle of felt to which I stitch the zipper, a course zipper is easier to stitch on and I stitch between each of the teeth where the two ends meet is the ideal place to add the cord hanger. My cross stitch design has been mounted ready on a small circle of cardboard, Stitching this onto the felt, I can place it in the centre or to one side if I prefer.
Back with a slightly smaller circle of cardboard so it sits inside the zipper then sew a circle of felt on the back
This one was edged with a finer zip and I found it hard to see where I had stitched, I did not stitch between all the zipper teeth just spaced my stitches evenly.
Hope this is of use to some one ... have fun.
