Hurrah!!! Cheryl, that was the show!! I just looked at it again, took copious notes and made note of the show and its # so I can find it when I need it. That is exactly what I had remembered seeing. While waiting for the answer to this, though, I went ahead with the project I was making and just did some wider insertions which will work fine for my purpose. But what a joy to have this technique demonstrated again. Thank you to you, and to everyone else who gave suggestions.
