Seek and find with NO find!

I need your help . . . I really do.

Somewhere out there in "messenger bag tutorial land" is a technique for putting a zipper in using  separate pieces.  It looks something like this.

It's rather hard to explain, but I know if you've seen the concept, you'll know exactly what I'm referring to.  Would you mind sending me the link?

I've spent several hours searching to no avail.

And Dolly would rather be out walking in the rain rather than wait for me by the computer.

Thanks "sew" much.
