Pdf tutorial using Fretz mini-stakes?

Hello Gang,

Please forgive me if this is a silly question but I appear to be
having a bad-brain day and need a little help.

Recently I saw or ran across a PDF tutorial on using Bill Fretz’s
mini-stakes to form the hollow ring you see on p.90 of the Rio
catalog. It was a step-by-step document with a number of good
pictures. I think it was intended as promotional material for the
Fretz stakes.

Well, of course now I can’t find it. I’ve googled around, searched
the Orchid archives, gone through my history, etc but I’m still
coming up empty.

Does anyone have a URL for this document? If so I’d certainly be
grateful if you could forward it to me.

Cheers,
Trevor F.
